Hey everyone..here's the problem. I have an 00 Mystique 2.5 ATX and lately it seems to be idling rough regardless of temperature or time. No codes have been thrown,no starting problems, not idling low, just feels rough. Rough as in I can feel the vibration through the wheel and seat when I come to a stop at a light. I did a search and I can eliminate the fuel pump and serpentine belt since both of these parts are less than a year old. Any ideas? Oh yeah, the car has 143k on it and I've had it since 0 and I maintain the car well.
