I have a 2000 Cherokee that just had this code pop up after.
A code for #6 misfire was original CEL and fixed. All the plugs were in pretty bad shape..My bad for not keeping up on her.
Plugs were changed and Jeep ran better than ever with stock Champions installed
Reset CEL and afer 2 days spprox 50 miles. the CEL light comes up again. With same one as above posted.
This is ONLY in the morning -now colder here in the NE.
Reset CEL and the Jeep is great all day and evening.
Next day after a short 4 hr night park CEL lights up again at 4 am start.
Reset again.
just now at 1am I went out and started it and NO CEL --------YET. I will be leaving for work at 4am as usual.
Thats alot of info about this code.
Has anyone else experienced this ??
Maybe Have found something ??
I'll keep posting about this since I didn't have this CEL until 1 day after plug change.
