I have a 94 and when shes idling she purrs like a kitten. But, when I accelerate its like she looses power, especially on hills. Any ideas?

 

This usually indicates a fuel delivery problem. Start with the simple things like your fuel filter (s) If you have any part of the airbox modified go back to stock. Too much airflow will lean out the fuel mixture. Cold air intakes will often create this issue. Also try putting a can of SeaFoam fuel cleaner in a full tank of gas incase there are clogged injectors

 

MAF sensor, take it out and clean it! mine was doing the same thing..
