2002 wrx stage 2 tune by Ed

the car doesnt feel like it pulls the same.
i went down to gst and they said more air was comming out of the oil fillter cap than usual and the car has more idle vaccum than normal....=(

i compression tested the car and got 130 125 130 125
after a track day a couple of weeks ago my car misfired in all 4 while leaving the track.

it did it again yesterday at an autox event before i even ran (car had been idling for a good 30 minutes)


any thoughts on why it misfired?
anything else i should check?


thanks,
Theo

 

what CEL are you getting? my roomate is getting misfire CEL on all 4 cylinders as well.

 

oh yeah, what's your idle vacumm at?

 

Mods?

 

What did you use to scan the code?

Did you actually "feel" the misfires?

 

I'm guessing tubo-back and tune, maybe up-pipe

most likely an accessport since thats all Ed tunes with now

 

p0301
p0302
p0303
???? <- actual code it gave me (i think it means misfire in all 4?)

vaccum idle is one line below -0.5 on a stock laamco gauge (only like that about 6/8th's of the time though...sometimes it idles right on -0.5)

mods are spt intake/megan downpipe/vishnu uppipe/ apexi gt spec exhaust/ 3 port boost solenoid/ stage 2 tune by Ed

AZN heres a list of codes for future reference http://home.earthlink.net/~opiewho1/...obd2_codes.htm

did not feel misfires...but i dont really know what they feel like lol...so don't take my word for it.

 

i believe on the AP the ???? occurs when the SAME code appears twice on the list.

 

ooic ic


(al- yah scanned with ap)

so any thoughts on what could be wrong?

i was told that more air comming out of the oil filler cap means blown piston ring...however i kind of just gave it the feel with ur palm test against my friends wrx and it feels exactly the same.

I reset the ECU and it felt a better..but id still like to know why it misfired...

Thanks,
Theo
