Is this normal number 1 has a white jacket on it all others black

 

Cool, keep us posted.

 

Nothing wrong with Delphi eh , been around for long time

 

K in a nut shell is wow this thing rips , what the he'll is in those plugs , I bit improvement in deed .

Now for the downer , still nothing changes with the idle to 1500 ish rough with lite throttle .

Ya all still thing it's the coils eh ? Oh by the way cycling threw with the new coil did nothing .

My cost the the new coils is very good . 🤔🤔

Anyone check out the two pics I sent previously one was the coil wire and socket and one was the brand of coil pack .

Happy to say all that work was worth it , but still frustrated With this missfires

 

Holly shit !! That's not cheap .
I have a parts store here in town OEM replacement $50.00 ea

 

I'll never understand why people will cheap out on plugs for something that lasts 105K+ miles. Retail, the NGK plugs run for $60. They can be found on sale for less than $50. They cost less than $8/year for the average driver...

OP, you never did answer: what analyzer did you use?

Has the car run like this since you acquired it? Where did you purchase it?

Honestly, at this point, it's probably worth paying a dealer $125 for a diagnosis...

 

fair enough , well she has brand new ngk plugs and all I can say is WOW! A huge improvement. But the throttle just off idle is still there . This morning when she was could it was quite apparent that she started up roughly.

 

I will inquirer about the brand as I am not familiar with it . My Machanic used his snap on brand scanner

 

to be honest I really didn't notice it to much when I first looked at it , the car is in quite clean shape , bought it of a Machanic works for GMC out of Burnaby here in town .

Figured it needed a tune up , clearly it did . Proof being with the new ngk plugs

 

Wait, I thought you "cheaped out" and added the Bosch plugs yourself? So you yourself created the need for a "tune up"....

 

Be for I added the bocsh plugs it needed new ones yes , I didn't put in the ngk to start , my bad .
They are in as or last night

 

So over the past couple days the tighten fuel warning light keeps coming on , does this have anything to do with the rough throttle

 

Doubt it, but it does mean a new purge valve is in your future.

 

Did anyone catch the pic I posted on the coil pack wire on cylinder 1 ?

Today's update , installed new PCV vavle and new EGR valve.

Nothing changed , the evap should be in on Monday /Tuesday I also gave in and ordered all new coilpacks . Fingers crossed 🙈

 

All the time and effort and expense of parts that you've expended so far could have been minimized by a $125 dealer diagnosis....

Have you tried calling the mechanic that you bought it from to ask him about the problem and/or the harness?

 

i did and as typically , he's knows nothing . Will call the dealer today and set up apt for new weekend, to solve this once and for all 👍.
Think throwing new coils in , good idea ?

 

k all

So I took my tl into the dealership and had them take a look at it . Said as per there scan , all is running inside of acra peramiters. But did say that they that there was indeed miss fires present.

Made the suggestion to replace the coil packs
Get timing belt done

If miss fire is still present then replace injectors, knock sensor, APP sensor.
Said that the AF sensor could be contributing to it too.

I really need some direction here guys . This is starting to be not funny any morany

​​​​​​is it possible for an AF sensor to be acting up causing these symptoms .

Cheers

 

Update

Did the coil packs today , nothing changed what so ever .

Picked up new AF sensor today , thinking of trying it on bank 1 and 2 see if ones on the way out and if that doesn't help things

 

Why in the world did you spend a fortune on coil packs when you've already proven it wasn't a coil pack?

Post the diagnosis sheet that the dealer gave you...

 

 

what have I done to prove it wasn't the coil packs
The dealership said that's were they would start with replacement of the coil packs , and if that did not solve anything than to continue with items that I listed

Yes will do

 

I actually got then at cost plus 10% so it wasn't that bad

 

You bought one new coil pack and rotated it through all 6 cylinders and that didn't change anything, correct?

What did the dealer say about the "fuel cap" message? This was an Acura dealer, correct?

 

Yes that is correct , but the dealership said to change all of then either way , due to the fact that one or more could be acting up under load ..

The fuel cap message has disappeared, that was on and off for a couple days then gone .

I will post now the reports from acura to view

Ty

 

 

Here is one more of the reports

 

What it this guys

Ty



What has some one done here , is this part of the audio system ?

 

Where is their written analysis?

Again, what dealer was this?

If that is the passenger right kick panel, that's the amp.

 

I sent too print outs of the report earlier

Yes passengers kick panel ok so stereo the eh . Any idea what the heck they were up too

 

Sorry the dealership was Loughed acura in coquitlam

 

All I see is a bunch of numbers, I don't see any analysis/conclusion/recommendation...

 

The numbers are there scans

And as far as recommended services I did list those previously

I can take a picture and post here shortly if ness

 

your tighten fuel cap msg is normal, can be easily fixed for 40 CAD, and that's the amplifier for the stock radio system. Not sure why they would need to access that area for diagnostic testing (not sure what other wiring is in that area). Also, that print out of their testing doesn't say anything about their findings, you might be better off getting an explanation from them. Unless there is a member on here who can decode those

 

that's what I was hopping, if someone knew what there reports said . But then again if everything falls within there perimeters then it all would look normal right .

I showed my brother tonight at dinner and he said well we now know that u have miss fires on cylinder 5 and 6 so work with that . He thinks possibly injectors?
Said buy two new ones and see what it does .

Clean throttle body?

 

Update on my type s

So took it in to a performance tuning shop today and had them preform a full leak down test and scan

ResultS are that the intake ,exhaust and coolant and solid .
the pistons on the other hand are said to be some what not good .
Now my problem has been from day one miss fire on cylinder 5and 6 no know cause what so ever to date .
Ironically both cylinder 5 and 6 are above the passable allowable limits for the test . Meaning they would not hold the compressed air , all others are within limits .
Now my question is is this even possible that these two cylinders are actually causing my issues ??
What I can't understand is I did a compression test and got great numbers , absolutely not blow by ie burning oil , and get Greta gas mileage.
It just doesn't add up for me .
Shop says just drive it , it runs strong minus the above
​​​​​

 

yup first thing we did , practicality free lol

 

"The pistons on the other hand are said to be some what not good.."

In what way?

Sounds like bent valves causing the leak to me, probably from an over rev. And that would really suck, because if it was over revved by the previous owner, he certainly was aware when it happened...

You're going to have to pull the bank 2 head to know for sure....

 

as I mentioned my car went in for a leak down test witch will indicate, a bent valve ie not seating right.

the summary is . The top end is sound ( intake and exhaust ).
Coolant is sound ie head gasket is good .
the test on the cylinders found that 1,2,3,4 are all with in limits . 5and 6 are slightly over the limits when it come to blow by the piston rings , ie air could be heard coming out of the oil cap.

My question is, with that information would this cause my miss fires ?

 

Nope, engine sounds reasonably solid.
