Well I can't rev past 5200 rpm and I have no codes. Anyone have any ideas of what could be causing the problem?

Ok, now I am getting a code 31. I checked my MAP sensor circuit and that is good. I also tried another MAP sensor and still have the same problem.

I'm going to try a friend's ECU tomorrow and see if that solves it.
