04 Grand Cherokee - high idle, won't come down
Just did a 30k service on my '04 but have a problem. I changed all 8 plugs along with oil, filters. While I had the black plastic intake off, I sprayed some throttle body cleaner on the intake and cleaned it up a bit. Started it up but the idle won't come down below 1,200 RPMS (it's fully warmed up). The CEL came on and the code/error was intermittent misfire, cyl #7. I reconnected the coil pack wire, turned off the light and it hasn't come back on. Seems like it's idling smooth but way too high. Any ideas what this might be ? I've looked around to make sure everything is hooked up and the throttle isn't stuck. I don't think this is related but I broke the vac line connection which goes into the oil fill/funnel piece. I used epoxy to fix it for now (or maybe permanent) and it seems fine. Any ideas appreciated !
