back up a bit. who did the engine build? have all the computer inputs been checked and within spec? is the by-pass air control valve working correctly? basics will solve the problems.

 

ITs an Atkins Rebuilt that we (my buds and I) installed ourselves. We didn't take the car to any place special to have the computer checked out, after my oil pump went bad and I took it to a rotory specialist, he didn't mention anything about the computer. Possibly he figured they were fine. Everything is the same other than it being ported. But I can see, how it could affect things. So No we did nothing to the computer.
