Engine Performance problem
1988 Ford Tempo 4 cyl Two Wheel Drive Automatic 105KM miles

Hesitation and stalling at stop happens after car warms up 15 minutes of driving only sometimes and sometimes driving on highway stumbling. I replaced the ignition module and thought problem was solved but this is happening again. Could this be my fuel pump.

I put new distributor cap,wires, rotor,coil,ignition module,fuel filter,egr and still problem not all the time but sometimes after 10 minutes of driving or on highway. I checked the codes came up with:14,18 96

Hey,after all those parts i replaced i put a another fuel pump in and it was not it. I came to the conclusion that the only thing left to do was erase the codes and drive the car again. After this i checked the codes and came up with only code 14.Code 14 means usually your ignition module which i already replaced or the distributor pickup. I replaced the distributor pickup and my car runs great.
