I know, I know , it's been awhile
I had my mechanic
check it out, and he said he can find no codes, nothing wrong.
Does anyone else have this vehicle and can share their mileage? Mine is an 06 Jeep Commander 4x4 with the 4.7, 170,000 miles. Maybe they all get low mileage.
It is in the shop now with two broken exhaust manifold bolts.
