Well, I cleaned them and reset the computer. The car starts up slightly faster, and hasn't tried to stall will in park. It does sputter though when at idle at a stop light.
Now you said something about the belt jumping. Do you mean losing it's grip and slipping across the teeth of the pully?
As for the acceleration prob, I assume that you have towed a trailer or driven something with a heavy load before. The engine sounds like it is straining, and it wants to go, it just cant. I thought about transmission problems, but it is nothing like what happened at my work. We have a 01 ram 1500, and the transmission took a crap. It was stuck in second gear. Cost 2K to fix. My car is experiencing nothing like that. It shifts fine, it just doesn't want to go. Vacuum leak is starting to sound more and more likely.
