  1. ok, i went home to nj and got my motor finally, rebuilt block, gt 40 aluminum heads, e 303 cam cobra upper and lower, 1.7 roller rockers 24 lb injectors adj fuel pressure regulator, i believe it is a 73 mm mass air, but not sure, ok the car runs great, but after cruising home when i would come up to a light or stop sign and i throw the car in neutral, it revs up, and then dies. ill start it back up and it will start acting up. i tried turning the idle up so it would stop, no luck. i think my pressure is at 40 on the adj reulator. is it to high, anyone know what i should do. ****ing me off, ill mess with it tomorrow after work, but would like to get some ideas tonight. later tom
     
  2. Pull the codes. Clean IAB, sounds like it may be staving for air. Mixture gets rich, idle goes up, run out of air and dies. Sound about right?
     
  3. 40 is a little high but it shouldnt cause the problem. Try 38. But i doubt it will help.
