Ok, 95 Mystique, 2.5L V6. When I hit the gas I hear a very audible grinding noise that is constant. Its not the ABS grinding noise. It revs up and down with the engine. I also hear a whirring noise. The ATF fluid smells ok and loks clear. I sometimes smell a buring coolant smell, but am not losing coolant. No apparent leaks anywhere.

Not sure if related, but when I start in the mornings it wants to stall out when put into gear for the 1st time and when you accelerate in Drive for a few mins, sputters, etc. almost backfires it feels like. Then its OK.

I'm more concerned about the grinding noise. Any help would be appreciated. thx
