my check engine light keeps coming on and when i put the code reader to it, it says misfire on cylinder 4. i have the ott stage one kit in it. It comes wiht 60lb injectors and 2.8 pulley, if anyone knows how to fix this let me know

 

Did you talk to ott im shure they will be more than willing to help you

 

not yet was waiting to see if anyone had this problem first.

 

how long have you been running the kit before you had the problem

 

week or two. seems to only do it when i'm sitting somewhere and its running. after my cars is off for ten minutes it goes off.

 

check the number four plug are you running a one step colder? or stockers

 

yeah i would double check youre plug

 

i have. i'm running one step colder gaped at 35

 

so u getting the p0300 code?

 

p0300 is random cylinder misfire. p0304 would be cylinder 4.

yea, check your plugs. i myself run .038" gap on ngk bkr7e plugs without issues.

 

I also have a tuned PCM from OTTP and I put it in today and drive home and my engine light comes on and It is a P0304 misfire cylinder 4.... What could it be?

 

same secnario check your plug

 

Did you guys do a case relearn when you installed the kit?

 

ya theft and crank relearn... came on I erased it and then drove for about half and hour... I'm still on stock plugs and NGK 1step are on there way

 

Could be the plugs, but it's weird that it's just the one cylinder like that. It happens when it's running, not just at idle, right?

 

no it only comes one when its idleing, happened again today... WTF dont want to hurt it

 

Try swapping the coil packs around then the plugs and see if the code follows. If it doesn't follow it's likely the tune. I run 1 step colder plugs at .035 and I used to throw a P0300 if I idled for like 2 minutes. Retuned the car and haven't had a CEL in a while.

It's a 60# injector + idle thing.

 

well u need to do whatever lil tune changer on mines so i dont get that damn light on again haha

 

ya ok I try that... thanks for the help

 

Ok so I put my ngk one step plugs and gap at .35 and I moved all the coil packs around and still getting P0304... Eny ideas's? Happened after I installed 60's and ott tuned pcm

 

bump

 

It's a known issue with 60s. Contact OTTP and see if they can help you out.

What pulley are you running? If you're on a 2.8 or larger I'd say try regapping to .036-.037

 

Check the O-rings on the injector and the injector seat or w/e it's called. Make sure it isn't cracked or anything.

 

^^^^check your injectors/#4

swap it like you did the plugs/coil.

60s aren't the easiest to tune at idle.

 

I e-mailed them and he said to check the plugs(brand new just put them in), swap coil packs(did that), swap injectors (have yet to do that), or a compression test.. what will that test tell me, the car was running fine before I put the pcm in my car it only has 21000kms on it I think it is the tune but the shitty thing is that I dont know a local tuner so I am pulling my hair out on this one... I am also running the stage 3 pulley 2.99
If i have gapped my plugs at .35 is it possible to gap them larger now?
Thanks
