I have a 2001 manual and I notice this problem yesterday. I had my AC oto defrost. The AC work at time but at times didnt do it's defrosting at all the it got real humid inside to a point that I couldn't see a thing out the windshield.

BUT the real problem I notice is at during that time the engine got real noisy like someones pressing on the gas in neutral which I wasn't I was at a ful stop. Also after that incident I notice that everytime I release the gas padel RPM surge 500 to 1000 before it drop. It's really strange. Isn't the RPM suppost to drop the moment I release the gas?

At this point it's not really that but of a deal but I have a bad feeling about this. Could it be the clutch wearing out? or is it a enegine problem? or maybe just electrical problem? I really don't know but this is not the 1st and I help some of you know the problem and can help out

Thanks
