I finally solved my random misfire that was only occurring at idle. Hopefully this will help someone else. The issue was that my timing belt had skipped one tooth. The rear driver's cam cover was cracked and a piece of it fell into the timing case causing the belt to jump a tooth. No more misfires in the past 3 weeks. HTH.

thanks. something else i have to look for. how many miles did this happen at? what other problems did you notice besides the misfires at idle?

 

The idle was quite rough but it never stalled or anything. Whenever I pulled the misfire code it was ALWAYS at idle although I had seen the CEL blink at high RPMs before as well (indicates real time misfiring). This started to happen at about 75K miles and I had an accident at about 60K miles where a guy hit me on the left-front. I believe this is what originally caused the cam cover to crack. Other than that the car seemed to run fine... I'm extremely lucky I didn't wreck the engine. There was a pretty big chunk taken out of the timing belt when I removed it.
