Guys, I found my way to this board searching for help. No, I don't have a Buick or a turbo and I sure not as quick as most of you. There is a world of knowledge here I can see. Bare with me and please help!
My problem is the engine is running lean after it has been driven awhile or sitting idling. I see this after my electric fans have cycled my voltage drops the ecu compensates, then when the fans cut off the engine is leaner than before. I have to go into the fuel map and raise idle a/f numbers from 55 to 62 for the engine to level out. A/R ratio is 13.5 but moves to 14.9-15.5.
B to B F.A.S.T. on a N/A 383 with wb02.
IAC is not active after warmup
Throttle follower is at 10 at idle tps position
42lb injectors
1200cfm accel tb
525 lift 219 dur.
1.6 rollers
Battery in trunk, ecu connected per instructions
Internal regulated alt.
