Hey guys, this is not my Jeep but it belongs to someone important to me. She bought it new and has 44k on it.
Naturally, the first check engine light came on while I was messing with the manual mode for the auto trans... Miraculously, I was not blamed for the check engine light.
It's just out of bumper to bumper but still under powertrain. Hoping someone on here knows about what's usually wrong with these Pentastars.
It throws a intermittent multi-cylinder misfire code that can easily be induced by holding a gear under load. Fuel economy is down, according to her, about 3mpg and it feels like it's lost power. I can confirm that it does feel like there's something up with the engine on a hill and the idle seems off to me but I don't know what's normal for a 3.6. In the past few thousand miles it's also lost about 20 oz of coolant from the reservoir that I filled up a couple months ago when I replaced the air filter.
On my scan tool I can see the long-term fuel trims while driving are off about 8-9% between the two banks. Catalytic converter temperatures are the same though. I took out one spark plug after it had been sitting for over 24 hours and it was totally soaked in fuel. More than I've seen on any fuel injected car or even carbureted car.
I could already tell from the phone call she had with the dealer that they were trying to brush off the problems. I want to be informed so I can blast anyone if they try to downplay these issues. I saw a ton of complaints about multi-cylinder misfires on the Jeep forums but never any resolutions.
When you cold start this Jeep you can see a light haze of smoke in the xenon bulbs. If it is an injector problem I think they should do a compression test at FCAs expense. Kind of wondering if a cylinder has been washed out enough to hurt the rings.
