cyl #2 misfire?

TuffStuff · 05-22-2008, 06:01 PM

Do I need to worry? I think the code was p0302 or something but the ap said cyl #2 misfire....I have an 07 so I'm pretty paranoid....

Grey Ghost · 05-22-2008, 06:24 PM

misfire on any cly should worry you....i guess i dont know how much money YOU MAKE>.... but subscribed cuz im not sure what that means for cyl #2

TuffStuff · 05-22-2008, 06:27 PM

this was at idle tho...maybe its a clogged injector? the car has a little vibration in it since I beat on it last week and today when I let it warm up the CEL popped up so i cleared it reset the ECU drove it around for a bit till like 40 miles then beat on the car again and now it seems OK like no vibration? Do I have like a dirty injector or something?

I have no clue.. but your power seems low for a 07 protuned stg2 wat psi ..u running?

TuffStuff · 05-22-2008, 06:44 PM

19psi on a Japtrix mustang dyno

Grey Ghost · 05-22-2008, 07:05 PM

ok that might explain the power....the mustang dyno is the dyno that reads low numbers right...?

TuffStuff · 05-22-2008, 07:17 PM

the power is fine its the misfire im ****tin bricks about lol. Its powerful enough to run with the evos and stis down here.Yea the mustangs are rumored to read low.

Grey Ghost · 05-22-2008, 07:24 PM

May have foiled a plug. When doing a compression test on my buddy's 07 with him, spark plug was cracked unknown to us then after reinstalling plugs and going out driving, he popped a CEL. Swapped in an extra plug I had and all set.

I know this may be a little late, but at one time I was getting a misfire on #1...kinda freaked me out until I talked with Scott Seigel at TopSpeed...I was setting up a Protune with him at the time.....anyway, he was almost willing to bet money that it was the injector...it seems the stock ones aren't really known to be completely trouble free on some of our cars...and, as additional food for thought, I run a bottle of injector cleaner through the car every oil change...no more misfires.....I did forget to one time and about a month later, guess what...misfires....just figured I'd throw that out there....

I wouldn't be too worried about. Just keep an eye out for it if this problem replicates. I have had numerous cylinder missfires in the last 10 months or so. I was told that it was aftermarket fuel injectors and it will happen from time to time.

i wouldn't say you dynod too low either, 313whp is not a bad power number for stage 2 07 or not.
