Rough idle / pouring smoke / misfire problem
I pulled the spark plugs the first sign of this issue. The codes for knock sensor and misfire and O2 sensors codes were all bank one codes. And if I'm right that's is the driver side banks (again I'm fairly knowledgeable on basic engine maintenance for most repairs outside of the internal block...- HighestStorm

Rough idle / pouring smoke / misfire problem
The initial reasoning for the maintenance that I have done so far was because of the flexplate being cracked but I didn't fix it and I continued to run it with the flex plate issue, see attached images, for about 2 months I ran it. During those two months it progressively got worse, some of the...- HighestStorm

Rough idle / pouring smoke / misfire problem
I don't have a scanner tool like that but I know people that do, I will check with them to see if they can run the tests but look at my previous comment that I just posted, the only time that it runs like this it seems like at least is whenever it's either low on gas or it started on a steep...- HighestStorm

Rough idle / pouring smoke / misfire problem
Yes all of the coils and spark plugs are connected but the coils are $220,000 Miles old but look at my previous comment that I just posted maybe that will help pinpoint it more if you know about these engines I would appreciate the advice.- HighestStorm

05 Yukon XL 4x4 Rattling in bellhousing area with AC on
If the tensioner and new pulley doesn't fix the issue I would say take it to somebody who can drop the transmission if you can't or drop the transmission out yourself and have them check the flex plate/flywheel. If you look at the pictures I just posted you'll see what the cracked flywheel/flex...- HighestStorm

05 Yukon XL 4x4 Rattling in bellhousing area with AC on
Just got everything repaired. The rattling noise was the flex plate, and the starter solenoid was going out due to the flexplate being cracked. And the sluggishness when giving gas turned out to be the rear knock knock sensor being corroded with water. The knock sensor being corroded fouled out...- HighestStorm
