Thread: Still having KR issues

At idle stopped at a red light my fuel trim is 12.5

ill have to use my paddle shifter to keep it in 3rd but I don't even think I need to since its rich way before it shifts into 4th. im going to baby the car for a bit till I can get this issue figured out. I'm really hoping with everybody's here we can resolve this.

just to clarify, did you mean to say +12.5 or -12.5. does your car have the option to shift into 3rd gear with the shifter? just do that instead. having your fuel trim at 1.56 is good.

I meant +1.56 at cruise and +12.5 at idle.

since my car is the Comp G the shifter only has "D" and "M" (to activate the sheering wheel paddle shifters)

is your pcm stock still? or it a canned tune?

its a canned tune from Overkill.

ill look far a vacuum leak when I get home today. it still idles smooth though

I looked at my vacuum lines last night and didn't find anything that really stood out as being bad. I did replace a dry rotted line that goes to the SC by-pass actuator but that didn't make a difference with my fuel trims this morning. ill check the line going to the fuel pressure regulator next but I have to wait for the rain to stop.
