When i rev it will slow at 1000rpm then fall if about to shut off.then stay around 500rpm i took off maifold and cleaned ports as well as throttle and icv.Still same thing.Idle dont move around just stays at 500.sometime it take 2 , 3 time to start and feels shakey wen i get it to start.

 

O i drive a 99 tl.(navi)

 

No codes? How many miles are you?

Check out the seafoam DIY in the DIY section.
Suggest gas tank and vacuum line methods for a good cleaning.

 

on the egr cleaning- you removed the manifold from car and got the passage all the way thru the length-to the ports under egr valve-with a wire coat hanger?

and the single egr port into manifold system? it should have a smooth bore metal sleeve inserted (recall) in the port to reduce edges for exhaust crud to grab onto and clog
fully cleaned, the port on engine block side knocked the stuff off and vacuum out?

and IACV - removed out of TB and cleaned slit?

how did all those parts look?

all vac lines ckd for loose fit?- split end of tube at fitting etc

spark plug age and correct ngk?
ignition switch replaced? had a recall on them and tend to fail again

since you are in Ca you cant go to parts store --need to look in Regions section and find ziner near you who owns a scanner..I Hate Cars is in B-field and a major guru of TL
could have a bad coil from the sounds of it,
does the rpm jump -range?

often worth the 100 bucks at harbor freight tools for the obdi2 scanner, so you can troubleshoot at home
get the codes and we can point you in the correct direction

 

seafoam note: many are afraid to do the vac port method, so a good alternative- per seafoams tech rep on phone = buy 2- 16 ounce cans
Add 1 can to 8 gallons gas, thats just under half tank, and drive however you like.
trips of more than 30 minutes help it work even better,,heat and time are seafoams friend

next tank, drive down below half and add the other can

Still need to clean TB air plate, no method gets that besides direct action

that takes care of everything you want cleaned, just not instant intake valve and piston cleaning like vac port does- literally in seconds!

it gets all the vac port stuff and all the fuel system parts
clean injectors being very important, without any concerns of CEL, hot foot afterdrive, and all the other things required of vac port method,,
keeping it simple for the masses~

 

Its a little over 290,000 i no that alote i drive pretty good. Okay i did not do the hanger all they way through ill open manifold up again and do it. You said something about coil can cause that problem if that were the case i would i find out witch one it is.I will clean today and keep you up to date. And i couldnt thank you enough for the information.

 

if the egr passage was not cleared you have not cleaned the egr system
and can expect running problems until its done right
especially at your miles!!

 

Man i just broke one of my spark plugs in the block i mean half of it there is no possible way i can pull it out with anything.What do i do. is it worth fixing if so how

 

the spark plug broke in half? so all the threaded part is still in there stuck?
no hex shaped part for the plug socket to grip?

or it broke in half vertically so half the threads are in the head and the other half in your hand?

if a spark plug socket wont get it out, you have to remove the cylinder head the remove it

plug was stuck- was it old,, or newer and just way too tight?
that can cause running probs
old plugs die

 

Not sure maby older and 1/4 of the thread is in my hand so. so should i just get another engine with lower mileage. What should i do im think more towards engine one of my friend said they will put it in.what does an used engine go for.should i get one off ebay

 

im pretty sure older

 

ck junkyards/auto dismantlers in your area
but any you buy will need a timing belt/ water pump job- adjust the valves etc
and still be unknown history of overheats

yours at 300, assuming kept up with oil changes and wp/tbelt replacements
should be fine inside, at 200 it looks new

but if you can find a 100-150kmiles engine for 500$ and 300-400 in parts to make everything trouble free, thats not a bad investment

tip for others changing plugs- spray wd or other penetrating lube into the plug area and let it sit for a while

to have one snap as you say- would lead me to suspect cross threaded at last install, or been in there so long that corrosive bonding took place
another great reason to use a little bit of plug anti sieze on install

 

you already had the manifold off- not much more to remove the entire head in question and have a local machine shop remove the plug

they may have to insert a new threaded section in the head, no big deal for them

 

well im tryan to take head off my self.so far i almost got it off.well be for i started taking engine apart i tryd using one of those easy stripp bits to stick down middle of pluge but it just broke off in there.Im taking picks so ill post them up if i fix it or i dont.I have a feeling im getting an engine at least ill get some practice on this one.

 

Idk if its possible for you now but maybe a flathead screwdriver and some good whacks on the top of that plug to make an indentation so you can turn it with the screwdriver might work

Show us some pics!

 

 

Well there is the easy out i tryd to get it out with

 

 

well i got plug out and my head gasket still looked really good so now to put it back together. man i wish i took way more piks so many diffrent parts to put back on

 

Good work!
This is good practice for getting to know the TL.
Do you have a service manual and all the torque specs to put it back together?

 

Yea i got the book the problem is i dont have to much tools.man i feel like giving up got my popz helping me.but damn itz alote harder to put together. still tryin

 

The head gasket is in good condition LOL and the shop i took it to said it was out they were 100% sure. when i kept overheating i would of lost out on plenty of cash if i let them fix it.

 

good condition? NOT!!
cyls 5 and 6, the center and right as shown in pic
are `steam cleaned clean`,,meaning there is water leakage between them- at the gasket

note the condition of the other piston with heavy carbon layer
and the head, see the 2 cleaner ones?

these pics are a good example of why seafoam or BG are important treatments
many think modern engines run clean,,not so~
clean = better combustion

 

go borrow a torque wrench from parts store, or buy one at harbor freight tools or sears
Torque on the head bolts is CRITICAL to the survival of that gasket
same for intake manifold and its gasket

Many head gaskets are a `crush type`- where they slightly compress with torque application, so its a one time use item

Never in my life have I reused a head gasket,,waaaaaaay too much hassle to do the job over
the head comes off- ck for flatness- new head gasket, new oil and new coolant
new spark plugs

 

well it rained and i was wipping it down maby thatz why is looked like that. I will be getting heads recerviced.as well getting internal realigned as well a head gasket kit. most likely i wont get it done till sat or sun put ill make sure to stick more piks up during process

 

or it could explain your overheat prob and poor running!
you wiped the head in a way to clean the upper portion of the 2 cyl in pic?
the pistons I could understand but..

all new gaskets etc,,good plan!
torque wrench purchase- do it!! 15-20 bucks harbor freight or 25 sears

 

if the timing belt is more than 60kmiles old, and you have all the covers off,
for $250-350 in parts, you can do the tbelt water pump job- especially if history of overheat

realign what internals?

 

Well so i decided to take engine out because a hair line crack on front head.So ill be putting a used engine in

 

 

 

Ill be re using tran.

 

lol you thought there were a lot of bolts just for the head!!
hope you learned to use parts boxes and keep bolts organized when there are different sizes/lengths used in some places

how many years did you drive with an overheat prob?
that will crack a head for sure

 

grab a can of CRC electrical contact cleaner and spray every single electric fitting you can find
cleans and protects really well

 

crc thank for the heads up ill be sure to do that.O and i gotta wait over a week to recieve my engine well that sukz.Ill be sure to put pikz up maby it will help some1 someday.

 

you are planning on installing a timing belt and water pump kit right?
new thermostat is always smart too
you have no idea how the engine was abused~

 

Ya ill be putting nu timing belt as well as nu water pump and replacing some of my hoses all new spark plugs.My coils on my engine are still good will be reusing those and when i get the engine i will clean inside manifold
