Ok here's the setup s13 hatch redtop Sr20det stock with gt28 except 9.1 compression.
When I start the car turns over good and stays at about 1000 rpms and a/f ratio at 14.7 after about 10 seconds car starts to get real lean. If I even attempt to touch throttle it will get incredibly rich for couple seconds then back to lean..
I've adjusted my tps to .45 and when i w.o.t. it only goes to 4.02v not 5..
Also checked the maf and I'm getting 12v power, with key in on position my signal wire is at .08 and with car running my signal wire is 2v...
Also idle boost is at -.5 bar..
Any help guys?!
