Ok last night i was running at WOT and then the check engine light started to flash, today the same problem on the same conditions running at wot and the check engine flashing again. So I put the scanner on the car and the problem was a misfire on piston # 1 and # 5 and multiple misfires. The mechanic told me that it must be the spark plugs my car is a 2004 with only 60k miles. Had anyone expirience this ? Right now the car is running fine but I am worried it could be something else, any sugestions ?

 

i have read a lot of misfire problems with the tl because people keep WOT-ing it. What is the point in WOT-ing the car? i dont get it. Maybe for Vtec exercise? but still......

 

^^^ WOW....

to the OP...have u every gotten you spark plugs changed ??? maybe its times....switch to NGK irridium plugs and see if this happens....it shouldnt happen regardless but what i can say is try switching ur spark plugs !!!

nope i have never seen this problem but heard stories about it !!!!

what was the error code ???

 

Really?

 

I never see it either. Sometimes the triangle with the ! when I hit the rev limiter but never the CEL light.

 

OP email OPEL or I Hate Cars or stillhere

they have loads of info....they will help u out !!!

 

no they are the stock ones, they are not supposed to be changed at 100k ??

 

well not really because the check engine didn't appear while acelerating is start flashing after !!

 

I really don't know the code the mecanic only told me that the reading was a misfire on piston # 1 and # 5 and multiple misfires. my only concern is that the problem are only the spark plugs and nothing else. Because I was thinking that at 60k miles they should be good.

 

a lot of people here switch plugs every 50K....some dont touch em till 115K....i personally have done it 75K and will do it again at 150K....

 

these are the plugs right ?? NGK IZFR6K11 Laser Iridium Spark

 

Yep, that's right:

 

I will order them tomorrow, i hope this is the problem.

Thanks a lot to all !! acurazine is the best !!! jeje

 

Forgot: Don't gap them.

 

I should probably change my plugs at some point.

 

same problem I had last summer. Changed spark plugs and everything was fine. front middle one was loose for some reason and was missing part of the half u looking thing at the end, its late and im tired. Everything is better now, even helped with quieting down the pinging. I bought them for 100 bucks the NGK upgraded ones from napa. Had 1k miles on them then went s/c and no longer need them PM me.

 

yup that is the right plug

are u kiddin me !!!! these come pre-gapped !!!! .044 pre-gapped !!!!

 

So i change mi sparkplugs today and they were like yellowish they ask me if i have added a fuel treatment to the gas. and i told them that i have only added the seafoam, they advice me not to add anithing to the fuel that it was not necesary.

 

dude i use seafoam every 5K miles

but honestly, i think the spark plugs were gone....so does ur car misfire any more ???

 

Right now is running fine.

 

on the contrary, I wonder why people don't WOT'it all the time. We didn't buy the TL to drive it like a chevette - its built to haul butt and corner on rails...in luxurious style. I've read more than a few times folks saying they never exceed 3500 rpm's. What!?

 

The TL has a great engine few other 3.2 liters produces 270 hp. my 2000 v6 accord is a 3.0 and only produce 200hp and even the 3.5 engine of the maxima is 255hp. if you have the power use is !! LOL

 

so basically you drive Ms Daisy since you bought you car? you never once went WOT in your car?

you only need to rev up to 5200rpm at the most to engage vtec and that does not require WOT....ive never heard of a Vtec exercise. vtec works mainly off of oil pressure and a few other things....

 

Nope, just like I said, don't gap them. A few people have made that mistake.

 

TL on "20" are still having the problem since you changed your spark plugs? because I have the same problem as you with my 99 tl..it started to happen I just finish changing the valve cover gasket and oil.

 

Nop! the codes have not appear again, try changing yours.
