It’s a daily driver, so I’m not looking for anything that’s going to burn the rubber off my tires. I’ve...

    I’m at a loss. I have a 2011 Tahoe z71 that we purchased a month ago. Truck has 165k miles. It started running rough at idle and seemed to be getting bad fuel mileage. On cold starts it seems to run great and after warming up it gets a slight rough idle. Seems to lighten up when placed in park...

    Oil not showing full on dipstick until 9 qts. were put in

    Hi all, I've got a 2004 Tahoe LT with the 5.3L. Recently I took it in for an oil change at a jiffy lube or something similar (I know I know, but I needed it done quick). They gave me the car back and were asking me if I had the 5.3 in it and if I had an aftermarket oil pan or something. I told...
