damnit! i threw a code last night and its still on. went to check it this morning and its 71. #1 cylinder (or random) misfire.

also throwing ATTS code #33. but the helm manual says for it to be ATTS Code 33 the CEL would not be on. just the ATTS light....


so what in the hell do i check for #1 cyl misfireing?
all the plug wires look ok.

here are what the plugs look like.

#1

#2

#3

#4

 

Try a friends distributer on your engine.. that might help narrow things down.

 

didnt you put the prospeed header on your car. if so it leaned the **** out of my motor. i would suggest putting in ngk's and haveing your car tuned. those plugs are lean. it is possible that you have a lean misfire code. and being on cyl one would make most since seeing how more air is supplied to that cylinder than any other.

i havent tuned mine yet but i had to bump the fuel pressure from 44 psi to 51 to get the plugs looking right. i have a 4th gen also.

 

yeah i did put the prospeed header on and it does look like it leaned it out a lot.

after calming down i went and rechecked the code and i was misreading the last one as a long, when it is really a short. so its actually 61 which is o2 sensor. but i have the o2 sim installed so who knows what the hell is going on.

im going to go out and check it again in a few lol.

thanks for the replies everyone. sorry to waste your time.
