'00 Expy w/rough idle
Okay, I fear I may have caused this...
A few days ago, I cleaned my engine, but left the hood up and in the sun for more than 6-7hrs (to dry). More than a full day after, she started idling very rough, and when at lower rpm, runs very rough and rich. I took to AutoZone, the findings were a "cylinder 1 misfire" Now I realize I probably did this myself. My question is: "What is it?" Could it be something as simple as a wet plug, or something more serious? It's now 24hrs after this began, and the idling is much better, but running at low rpm is still at issue at times. Also the service light remains on. Can this be reset by removing the battery cable(s), is there a better way?
Thanks,

Basically you probably need to replace that COP. Very easy to do since its the #1 COP, be glad its not the #3,4,7, or 8 COP. Go to the auto store and get a new COP, remove the plug in electrical connector, the bolt, and pop it off. Depending on the store you get your COP from, it may or may not have the boot and spring on it. If it does not, then pull the old boot and spring off (pull the spring from near the connector and not the end, so you do not stretch it.). Replace them on the new one and pack the end with dielectric grease and re-install.

Thanks again!
