95 geo prizm hesitates

03-14-2006, 05:13 PM
I have a 95 Geo Prizm and have been having trouble lately. When it is cold and\or wet outside my car will not make it up my hill. It hesitates and wants to stop. This usually happens in the morning. Yesterday morning, I made it half way up my hill and the car was shaking and wanted to stall. When I came home in the afternoon, the car started and ran like a champ. In the morning, it was warm and humid. The afternoon was warm and milder. The same thing happened this morning-it was rainy. Later in the afternoon, again the car ran nicely-it was breezy and warm. I got a tune up in November-so the wires, plugs, and distributor are ok. Could it be an O2 sensor? If so where is it? Could it be the fuel filter? Again, if so where is it? Any other suggestions?

Does your car only have this problem when it is cold? That is, when the car is warm, will it make it up the hill?

If you've fixed it by now, what was your car's problem?

The problem was taken care of by getting a tune up and changing my gas filter. Thanks for replying.
