'97 cavalier- cuts out @around 2500rpms no engine codes. TPS & MAP are good- tested also replaced. BTW 2.2L w/ 4spd auto. fuel injector signal is cut at this point. when it cuts out, signal is restored engine speed picks up- then cuts. seems to be at a certain throttle position but have not only tested the component, but have put 3 units on it. fuel pump & filter are new. difficult to check pressure on this model but since the signal is being cut- it must be a sensor somewhere that is providing faulty info w/o setting a trouble code. should i try to set a code to eliminate the sensors? i really don't wish to do this. perplexed, Allen
