Ok I just recently had this issue. Car will not accelerate past 2500 rpm. It feels likes its ******* a ton. If I keep giving it too much throttle it feels like it wants to stall. It will stall out at low speeds. Any ideas? Thanks ryan

 

Will it rev past 2500 in Park? Could be fuel starvation or a plugged cat.

 

No it won't rev past 2500 in park either. By the way its a TBI motor.I haven't had a chance to check fuel pressure but thanks for the tip. Although I can see fuel being dumped into the TB maybe the pumps on its way out?

 

Thanks afremont! It was a plugged cat.
