I have a 1990 Tempo with a 2.3 litre 4 cyl engine. Vin has an X for those who can diferrentiate the type. It has developed an issue with stalling. It has no problem starting and running. The stalling happens when the car comes to a signal light or stop sign. When I try to accelerate, it sometimes stalls and dies. When I press the gas for, lets say, a fast start, it hesitates and dies. If on the other hand I'm easy on the gas and gently press the accelerator to go, it hesitates and (sometimes) picks up speed and the car runs fine. It runs good once it get's going. No sputtering or jerking exists. I've taken it to the Ford Dealership twice and they've changed this sensor and checked all the vacuum hoses to no avail. This all started after the Oxygen sensor in the exhaust manifold was replaced with a new one during the exhaust manifold replacement job. Does the computer have to be reset for the new sensor? Could the new sensor be a dud?
