92 5.0 tpi with new MAP Sensor and new long block engine. The car will drop rpms before on first acceleration but then runs fine. I have checked tps and map and everything is reading correctly. Ive been told to replace the eprom but I am tired of throwing parts at it.


Also, every now and then it will rev up and down on its own. When I go to put it in gear it stalls. It fires up immediately but once I put back in gear it stall again.


Can anyone guide me one either of these issues?
