How about plug wires? When you changed out your TPS, did you go ahead and
clean your TB and the rest of the sensors? Coil? Cam sensor controls the
timing to injectors. That would probably cause more than a stumble. I
would think that crank sensor would also. That's a Bernd question.

Subject: DML: Stumble on Acceleration
Can anybody help me figure out why my truck stumbles while accelerating? I
notice it mainly after a cold start, but it's intermitant. I just replaced
the fuel pump, plugs (correctly gapped) cap and rotor, and swapped out TPS
with an older slightly used one. No change. The truck continues to run
strong. No noticable loss of power, but the problem still exist. I've
checked for vacume leaks and also tried moving MAP vacume to the intake
manifold port. No help. I'm using the old F&B stage 2 T.B. Could there
possibly be a problem with the throttle shaft, cam sensor or crank sensor?
The pcm list no codes! Help!
