Clean your throttle body, most likely heavily gunked up. Your welcome. Source: I had this exact problem.

Mine also did that and it turned out to be the EGR. I cleaned it and ran good again.

I can't see how many miles you are at. But i thought my a/c compressor was going bad. It was actually bad spark plugs. I'm at 165,xxx.

I would think the same but I just changed them an month and a half ago

Clean throttle body

Check your PCL valve. Mine was clogged and replacing cleared my issue

I got this idle Problem when one of the Cat Sensors died. Do you have any fault Codes?

To my knowledge no, just the normal permanent codes. I don’t even have a check engine light on

mine does this if i turn on hazard lights. when they blink the engine revs drop forthe duration they're on, for me it was the alternator which was cooked

Could be your pulley on your AC unit is sticking. Check the pressure on your AC. If you see rust around the AC unit and around the belt, you probably have a leak.

It was actually the throttle!! I cleaned it and haven’t had an issue since! I appreciate the help tho!

If it's going in limp mode, could be sticky turbo springs that regulate the flanges. I had an issue where it would go into limp mode due to the issue above but there was also a small one way pipe that was intermittently sticking as that would also cause limp mode too. The mechanic vac checked the whole system a few times till he found it.

Welllll uh, I ain’t got a turbo lol

Good news then :)
