you could probably pull the air intake off the throttle body and take a look at the butterfly and see if it is stuck open or something, should be closed with engine off

This is a very concerning statement.I checked the dip stick, and oil was low, so last night I added two quarts just the same as I usually do.
That shouldn’t be any issue at all. You can safely run a quart or more over without any problems.Thanks everyone. After checking the dipstick, it looks like the oil is way over filled (well above the five dots on the dip stick). Hopefully just draining and changing the oil will be the fix.
Yeah thinking back on it now, I don't think I've ever added 2 quarts at the same time, so that was likely overkill. I've definitely had moments where it needed a top off before completely changing the oil though.This is a very concerning statement.
You should not be running that low on oil on a regular basis. That's how you blow up your engine prematurely.
i doubt it is the maf, when it is unplugged that puts everything else in default because it can't tell how much air is going thru the intake.Thanks, everyone. Finally got it into a shop, and it was spitting out a ton of codes. One mechanic had the idea to take off the mass airflow sensor (or some part of that system), and suddenly the revving while idle seemed to stop. They're going to start with replacing that sensor in the morning. My fingers are crossed that that's the only issue and nothing more serious. We'll see.
Great advice, and thanks for the tip. I’ll be sure to ask for the list of codes tomorrow. I appreciate all the help!I don’t have much faith in a mechanic that diagnoses a problem by unplugging something, seeing a change, and deciding to replace that part because of that. Ask for the codes at the very least so we can help you gain an understanding of what might be going on. It’s good for you to be educated on what the possibilities could be so you can make educated decisions. Don’t just take the word of someone trying to make money off a customer who doesn’t know better. You have a lot of knowledge here available for free.
