SR20DET lobes really bad... ideas?

[srJOEYdet]

Hey guys..

I just finished swapping my redtop SR into my BMW cabrio. It runs great for about 16 seconds. then it starts lobing really bad. It will go from about 800RPM to about 1300RPM, very consistantly, and it doesn't change.

I have not got an accelerator cable yet, so I cannot comment on how it drives.

THe ECU is throwing code 34 and code 11. code 11 is the cam pos. sensor. If I had a problem with my CPS, wouldn't the car not run? Code 34 is the knock sensor.

Other info- I have no EGR system, no vaccuum leaks, and the engine didn't do this when I had it installed in my S13. The engine speed is constant when you hold the throttle body open at any RPM above idle. IT only happens when the throttle plate is closed.
