I have been working on a 1991buick century limited with a 3300 engine. I was driving up a hill and allof a sudden the car slows down and when I reached the top it died. After I got pulled off the rode I started it again and it died So far we have replaced the ecm and the ignition control module. I did a diagnostics test on it and the codes I was given one of them were the tps throttle position sensor and another was the O2 sensor can anyone help please.

Sklotzner, Your lucky to have been able to pull a code. I would start with the TPS and check the wiring for shorts or opens in the circuit.
Normally an engine will run with a bad O2 sensor, but the TPS is a main component in the fuel delivery system and may require replacement indeed, Dog
