Hi guy! Got an 01 TL With a check engine on and it said cylinder 4,5,6 misfire!? Wtf the car run like new! So i decide to change all the spark plug (NGK) on all of the cylinder and rest the check engine light but it come back as the same code! got any ideas let me know...... BTW the car run Like new and there is no shake on the engine at all PLEASE HeLP MEEEEE.

 

change your ignition coils.. same happened for me.. changed spark plugs.. and still no go.

 

It's probably only one coil that's bad. Change them one at a time and reset the code in between.

 

or unplug 1 coil at a time and ck idle speed for slight drop-change

the one that doesnt drop is a bad coil

you installed the correct 8 dollar each NGK?

and reset ECU how--clock fuse? I dont trust machines for this!!

 

yea i had this same problem the other week. i was able to figure it out thanks to 01tl4tl! do what 01tl4tl said and check each coil pack while the car is running. no drop/change in rpm=bad coil. then yea just reset the ecu after u figure out which one it is.

as for the plugs its the NGK iridium ix ones so hopefully you used those.

 

what I know specific to the TL,,, all comes from azine reading,,,and picking fsttyms brains now and then,,
sorry about those cranium access portholes left behind kris~

 

thanks for the reply guys.... yep change the NGK plug that cost 8 buck each, but i got a 99 TL to so imma try to swap all the coil from that car to the 01 TL and see what happen. And i reset it buy disconnecting the battery is that ok? All So the car had transmission redone and when driving it the TCS light come on, is that happen to any of you guy after yall got the transmission redone?

 

back to the trans shop for you!!!

dont swap all the coils--find out which one ,,
if its a coil at all-- now that we know there is a transmission rebuild involved

You can reset ECU with NEG battery cable removal but that makes you enter the radio code
Lazy way is remove CLOCK fuse on end of passenger side dash
thats the secret backup power for the ecu and will force a full reset and relearn/self test
without disturbing the radio security

 

Don't replace all the coils thats a grip of cash unless your ballin like that. Haha but do what was said earlier and test each one that way if one is bad you can identify it which saves you from buying 6 new ones. Assuming any of them are bad that is...

 

note: he said he HAS/in possession of- a coil set off another TL engine,,
but why do all the work if only one is bad?

IF you are going to replace incorrect spark plugs--may as well throw on the other coils you have sitting around

again-trans rebuild may be at issue and cause false codes
a bad coil will usually show in slight roughness at idle or under full hard pulling load--the power just doesnt feel right

try the disconnect each one and see if rpm changes slightly
no change = bad coil

 

Imma try to drive it for a week and see what happen

 

dont drive it with a problem- find the coil if thats it--or get to the trans store today!!

 

Yea....not such a great idea...

Id get it fixed if i was you or at least try and diagnose the problem before driving it

 

ok ok guys i have good news hahahahahah So Saturday nite i swap all the coil from the 01 TL to my 99 TL rite... i didn't reset the engine check light rite and i also did the timing-belt the same nite rite,,,, drive it a liltle bit on sunday rite the check engine light still on, and drive it today the light went off!!!!!! hahah i was so happy and bring my car straight to the inspection and pass it......

 

You replaced the timing belt (rite)?

 

Congratz man! Cross your fingers and hope it doesn't come back.

 

thats great

If you had cleared the ecu --the smog machine will say it doesnt have enough info to read the system

 

@Karanx7 thanks man but i can care less if the check engine light come back on or not, im passed the inspection!! and 01TL4TL umm I Live in RI so the new inspection machine is provide by the state and they didnt hook up the smog machine at all on both of my TL man.

 

The RI inspection is the a real B I T C H!

 

lucky you!! dont have smog test machines!!!
(but ck eng lights are always important- dont ignore)

and DO the ECU reset with clock fuse now to reboot the system- it may run even better

in Ca we have the smog ck,, but dont have to pass an actual safety exam of brakes-glass-lights etc

they dont care if you die,,, as long as the car isnt putting out excess emissions at the scene of the crash!

 

@ 01tl4tl: dude Iknoe I live in CA id rather go through a smog chck than deal wit a yearly inspection of the car. Some cars are in horrible shape, but if they meet CA emissions its good to go.

 

Yea the inspection machine in RI is from the state so it is very difficult to to pass, The old inspection machine is easy if you know some one that work at the garage or pay them extra they can hook up a car the passed the inspection and let you pass. But the inspection machine in RI work by hook your car up and it automatic sent and store your car info to the state comp .... it a real bitch im telling you....

 

BTW guys who live in CA and worry about smog test , clean the intake manifold by take them off and clean it the car run alot better and do like a seafoarm too, and the 01 Tl that i have i need to to the timing belt again!!!! dam it.... i jump a tool when i put the belt on and the car run a lil bit aggressive

 

 

I didnt understand this part, but no worrys about passing a smog check, my cars stay clean and I really dont use seafoam only because I do not need too. I may one day do it for my integra feels a bit sluggish.

 

dont need seafoam? how is that? your car doesnt run on internal combustion?
byproducts of partial fuel combustion residue- especially thanks to E10 gas, make the car run poorly
Getting rid of that crud restores power and mileage

dont care what product you use but use something

 

TRust me seafoam does help some what but you get better result if you take the intake manifold out and clean it there a lot of shit in it, the main reason for me use seaform is to some what clean the o2 sensor and hopefully clean the cat a lil bit.... but hint! after let your car intake seafoam for 15 to 20 min don't rev it up to hard or step on it when the engine first start....


99 TL 2002980K original engine and tran and the fastest i have done on it is 130MP

 

So should I really consider doing the seafoam treatment on my Integra. I just hate the slow acceleration or passing power. As far as my TL goes it runs fine so I do not think that Acura needs it as much. Would like to see a difference in my integra.

 

What kind of seafoam brand would you recommend to do this, I have a tendency to screw even the simplest of mechanic work. I usually go to my uncles shop to deal with issues. I really should read the manuals for both my cars and get more acquainted with my cars.

 

both cars NEED it- if they run on usa spec E10 gas,,you will be pleasently surprised for the TL to be smoother and faster, better mileage etc

the seafoam diy describes in detail how to restart engine:
idle-just above idle, let it get smooth enough to freely rev to 2000, then drive in lower gear- 2000 for a few minutes as smoke spews

when engine is back on close to 100% gas- will rev to 4k,,then its time for a few minutes of that rpm and some vtec runs for play~~ keep under 5k as crud is moving out.
5-10 drive minutes.. and all is well for the blowout drive

I suggest add seafoam to gas tank before doing vac port, so its working the whole time.
Reminder- if in any doubt how to do vac port- use gas tank method twice and get better results than just vac port
NEED to do gas tank regardless of any other methods
AND need to clean TB air plate

 

mando--seafoam is a specific brand name, you can buy at most parts stores or even walmart (cheapest)

get 2, 16 ounce cans for about 7 to 10 dollars each,
special this week at Oreillys buy 2 get 1 free-20 bucks total

for you with doubts on your own skills: do the 2 times in gas tank method
thats better than just vac port and will subsitute for vac method no prob, and clean more parts

wait till a little under half tank of gas and pour in the whole can of seafoam.
repeat on another half tank and you are done- good for 1 year/15kmiles

Do clean the TB air plate with carb or TB spray cleaner
have to remove the air tube from air filter to engine--the air plate is inside TB

your friend can help or do for you in a few minutes

 

Mando-if you really are 05,,try 3rd gen thread section- this is gen2 '99-03 cars

 

@01tl4tl

Iknoe I want to but for some reason they all seem really angry with new post being made. I tried the search button through google but not getting the results I am looking for. Sorry for busting in on another section. did not plan to really focus on seafoam, but rather just make 1 or 2 comments on the topic.

 

LOL, they need an 01tl4tl in 3gen! Time for a new car Tom?

 

Mando, try this: http://www.youtube.com/watch?v=dQ1wpO6Oj8E

It looks pretty similar to 2gen TLs. Google "2005 tl seafoam" and you'll get all sorts of hits. Usually google is better for searching Acurazine than the Acurazine search but it didn't get a lot of hits - maybe the 3gen guys aren't as "into it" as we are ...

 

I helped write the gen2 and gen3 'foam diys~

as long as you try search and scrolled thru the main and problem sections for your answer
then new post are no prob

If you ask the same question we have all answered 4 thousand times already,,,
and a main thread on the subject is 2 lines below your new post...
then you may get some 'tude..but its in good nature

the seafoam procedure is the same between gens, the only thing that changes is exact location and direction the metal tube from TB is set--that you put seafoam into.

Note: its SO much easier to control with a self made spray or deep creep can,,
sip sip sucks!! spray spray rocks!

I used to spend time in gen3 after working on local ziners car- seeing whats the same
but if I got one little thing wrong because 2 and 3 differ- how those dramas do unfold~
so I hang with my own kind now
next car not a gen3 or 4-not impressed with them-see their prob sections for why!
a caddy cts would be nice

 

just ck'd the vid--good instruction except needs throttle held up by helper in gen3 (fly by wire throttle) while we can use our hand to manipulate the return spring/cable assembly to keep about 1000-1200 (plus the 2000rpm sets)--
the springs also needs some clean and lube= that sprayed seafoam will do

other prob on vid is end- says ok to rev in driveway NOOOOOOOO NOOOOOO NOOOOO
dont do that!!
see my many post on the subject of restart after 10-15 minute percolate time.
More time than that allows too much cat and engine cool off= we want to make heat right away and keep crud `liquified` (seafoams description) and blown out the system

Note the smoke is really oils in seafoam reacting to heat in cat- not indicative of actual dirt level...no smoke means no heat --not no dirt!

 

Mando what were your intended comments? beside question of `what brand of seafoam`-- lol--sorry tooooo funny to those familiar with the product

do some net research on seafoam- a chemical engineer working on personal project to clean the sea salt crud from outboard boat engine carbs-offshore ocean racing is murder on them
Found the right amounts of 3 very basic ingredient oils- each with a specific task, soften/liquify-clean-lubricate
that has been a mechanics favorite for 50+ years with no change to the formula except when govt thing about coloring agents changed-- so seafoam removed the dye..now it looks like kerosene..same ol stuff

techs will often use it to remove carbon and establish a baseline of cars situation from there
when carbon loaded its going to run poorly

 

AND YEA MANDO Make Sure YOUR CAR Engine is really really hot hot like after 20 - 30 of driving first... and then do the seafoam

 

@ 01TL it is safe to put seafoam in gas tank because the fuel filter is pager?
