Q: No acceleration after an engine replacement

asked by on December 09, 2016

I replaced me engine with another used one. I took off all of my sensors, relays, etc and inistalled on the new motor. After we got it completed, we went to start it up and the engine won't accelerate above 2200 rpm. Also, it will die out as well.

My car has 165000 miles.
My car has an automatic transmission.
