2006 LJ 6 speed manual.
My son took ownership of the Jeep last week as he just got his license. Him and a few buddies went out cruising. He called me after they had stopped at a gas station and said there was a check engine light. He was able to limp home. Read the code, it was Cyl 3 misfire. Cleared the code and drove it down the road, it felt fine.
2 days later, it does it again, this time, it is saying multiple cyl misfires detected. Clear the code, wiggle some things, take it for a drive, come home let it sit. Fire it back up and you could instantly feel it bucking but never threw a code.
I noticed that the temp gauge is sitting at 210, this jeep has never sat at 210, always a little less.
I changed the crank sensor and thermostat and burped the coolant system. Also added about half a can of seafoam.
He took it down the road, pulled in the garage, still running 210. I let it run in the garage while we look over things. I go to the back of the Jeep and instantly smell rotten eggs. I know this is a sign of bat cats, but could it have been from the seafoam?
The Jeep is a well known Jeep repair shop. I'm tired of guessing. They called me this morning and said they couldn't duplicate it. I told them to wait until later this afternoon when it is hot outside.
Thoughts/ideas?
