I have had a persistent problem with my car that is driving me nuts and Im looking for any advice. There was some conversation about it in my build thread, but Im still stumped.
Background info.... the car was tuned on 7psi on Neptune and had no problems. When I changed pulleys and went to 10psi I have had this miss at 6500-7000 rpms. The engine stumbles at this exact same spot every time. Its barely noticeable in lower gears but on the dyno or a 3rd or 4th gear pull on the street you can feel it stumble. I got a new 3 bar map sensor, new cap, rotor, and plugs, and wires.... none of this helped. The distributor looks like new on the inside, connections are clean.
Any ideas? I'd hate to buy a new distributor and thats not the problem either...
