I first want to say thank you for the great information on the boards. For the last several weeks my car has been reving to about 2500 rpm upon cold starting and has been running a little rough. Last night after 5 minutes of warmup the check engine light came on and has not gone off. I know it could be several things but my question is will this cause any engine damage? I can't get to my mechanic until next Wednesday and would feel more comfortable having the information. Also if anyone has any tips for remedying this I would appreciate it. Thank you in advance.
