Ok well ill explain what my problem is now a bit better. I dropped my fuel pressure to get rid of my back firing problem, this worked, I also upped my timing to 14*. Then I adjusted my air bypass screw? (one in my 70mm bbk throttle body) to get my hanging idle slightly lower. But ever since I did that its been idling funny, and I put it back to excatlly where it was. Anyways this is what happens... Now keep in mind I have a H/C/I 94 5.0 so I got the slight hanging idle issue. (better then it ever has been lately though) Crusing down highway, see red light, shift down, get down to 1st gear then put it clutch/pop into neutral untill I come to a complete stop....Now before I stop my RPMS hang for a full second at 1k rpm then drop down perfectly to approx 700 rpm...BUT as soon as I come to a COMPLETE STOP a second later they hop up about +300rpm then drop down to about 500rpm and the car stalls. Its weird because it doesnt stall untill I come to a complete stop I could be coasting down a hill in neautral and it will sit perfect at 700 rpm but as soon as I stop it surges up slightly then drops down and stalls. Now why not just turn up my idle via the throttle return screw? Because I did this, I set it to about 800ish rpm but then my idle would hang for about 2 seconds at 1500rpm then drop down to like 1100rpm hang again then finally drop to 800...this is annoying as hell, I would rather rev it at a light to stop it from stalling. ANY IDEAS?!!?!?
