Its been SO long since I have had a good running car so I kinda forgot what I need to do here. I FINALLY fixed my timing-ECT problem with a new computer....so now its time to start REALLY tuning. Heres my problem:
Right now im running a pretty much stock J4J1 with a few scalar changes for 42 # injectors, a generic 42# MAF curve, and a few minor scalor changes. If I start the car, it will idle pretty well until I touch the gas. Then the car will surge and either catch itself or stall. Also, when I get on it it will kinda miss/studder and sometimes pop. Basically the idle thing is what I want to fix first....how should I start? Should I tune with the tweecer or could it be a mechanical thing like the IAC or TB?
