My 97 tracer just started making a strange noise when the accelerator is pressed. It sounds like a hiss or slight squeal coming from under the hood. From inside the cabin it sounds like the fan on high a little bit. It began right after (or during) my wife used it on a longer trip, and it already had issues with being underpowered on the hills and having a slight knock. Thanks for any info.
