Hello, in previous posts engine will not exceed 2,500 rpm resolved. Diagnostic showed MAF sensor replaced $126.00.
Engine responds like it should. Finally. Now the engine hesitates when accelerating. Bucks upon acceleration until rpm's exceed 2,000.
The engine is rebuilt but does not have the snap it had before. Power loss is noticeable. Timing is very close if not perfect. Thanks for any and all replies. JC

Hello,

This sounds like a TPS sensor is not working right but we should run the codes to see what comes up. here are two guides to help us get started:
