Ok so it rained last night, and since I am pretty civilized with my car most of the time I decided to do a couple of doughnuts in an empty parking lot w/ my friend. about a minute after leaving the parking lot, the engine rpm's go REALLY low, then it dies. fire it back up, dies. So I figured that I got the cap/rotor a little wet, and fire it up in the morning and it should be alright.

You may have a bad temperature sensor. When the temp sensor goes bad on E30 M3's, it won't idle properly and feels as though you have a power loss. Also, check the flapper door in your air box to see if it is operating properly. You may have sucked in some water and want to check your air filter.

morning comes around same thing...hmmm, this could be a problem. if I keep my foot in the throttle, where it used to keep steady at 2,000rpm, it now cuts out, dips to about 1,100rpm then jumps back up to 2,000rpm. does this constantly, and sometimes dips lower. if I take my foot off the gas, it immediately dies before the engine drops below 1,000rpm.

nothing had improved since I got home from work. I have noticed that the carpet is also wet underneath my floor mat on the drivers side. Also I just put in a JC chip about a week ago. I'm going to re-install the stock chip and see if that makes any difference.

any ideas what the heck is wrong with my car?
thanks in advance
