Get something without AFM (AFM is in the 5.3 8cyl...failed lifters causing major engine overhaul or replacement altogether) Oil pressure and oil consumption issues (see pinned posts at the top of the forum) Dash panels crack at corners of passenger air bag and over instrument panel

Stepper motor for the temp gauge possibly going bad? That gen of GM products are notorious for stepper motors in the instrument panel going bad.

I'm using a ~10 yr old laptop, running Mozilla Firefox, with AdBlocker Ultimate and uBlock Origin with no ad problems, lagging, or any other issues.

Fuel pump/fuel filter (can't remember if the 01 has an external fuel filter or if it's built into the pump)

1986 Monte Carlo...I got it with about 75000 miles on it and proceeded to put over 225000 more miles on it. I sold it to my cousin and he drove it for several years before passing it down to his younger brother. When he finally stopped driving it, it had over 425000 miles and the only major work done to was when I had to have the transmission rebuilt. I bought my wife an 05 Tahoe in April 2005. It now has right at 310000 miles and still going strong. I've had to replace the water pump 2x and that's it. I'm driving it several days a week now back and forth to work

Are you talking about the handle to open the door, or the pull handle to close the door? If you're talking the pull handle, then, yes, you do have to replace the door panel or come up with a solution on your own, like this one... https://www.gm-trucks.com/forums/topic/188174-ltz-arm-rest-broken-replacement-ideas/?do=findComment&comment=2078372

You ought to post the question a few more times Both filters will fit and "be proper"...your choice as to which one you want to use based on your driving conditions (normal around town/highway driving, get the OEM...off road/dusty conditions, get the heavy duty service...only about 30¢ difference at RockAuto) A3181C is GM OEM filter A3085C is heavy duty service filter

Hate to break it to you, but, if that's for sure what it is, there's no way to "quiet the noise" and not risk more damage. You're looking at replacing the lifters and possibly the cam (won't know if the cam is damaged until it's torn into). Research AFM delete kits...I'd recommend going with non-AFM lifters, cam, etc from Texas Speed and Performance, though, there are others that put out the same kits.

CEL on? If so, what are the codes being thrown? Sound like this? If so, you have encountered the infamous collapsed lifter

The TPMS sensors are probably dead. You either need to replace them, live with the light, or get a TPMS emulator tool to "disable" them

XM is always free during Thanksgiving week and I think it's July 4th week.

Could have been that the battery cable was a little loose, and when you disconnected it and reconnected it, you got it tight. If it does it again, I'd replace the battery cables. They are known to corrode inside of the insulation. You can also check/clean ground locations. Have battery tested also. All of these can cause electrical issues like you are seeing.

Since there's only one person here that knows what year car you have and what transmission is in it, here is the info from a 2008 owner's manual
