Working on my daughters car. We have changed the fuel pump, fuel filter, coil, injectors, main relay and I am still having problems with rough running and stalling. Please any advice will be apprieciated. I have considered it might be the air intake tempature sensor too but I don't want to keep changing sensors with out confirmation and waste more money.

The rough running and stalling will likely be solved by replacing the Ignition Control Module (ICM) inside the distributor. Be sure to apply silicone heat transfer grease to the back of the new ICM. If the distributor cap and rotor haven't been changed in 60,000 miles, this is a good time to do it. High resistance in these items often destroys the ICM. You also want to verify that the Check Engine Light consistently comes on for 2 seconds and then goes out, when the ignition switch is turned to ON (Position II).

The check engine light has never come on. And we did change the rotor and cap when we changed out the coil. So we will give this a try. Thanks
