Thanks for the suggestions so far. The A/C clutch does kick off when you turn the a/c off. I considered the MAF sensor, but I was thinking it would cause some other performance issue as well. However, I looked at it today and I did clean the screen which was a little dirty. Tires seems to be wearing very evenly - car doesn't pull left or right so I don't think it's an alignment. No brake issues...all wheels spin freely.....appreciate more suggestions! Thanks - Tim
