RPM's stumbling, car stalled. didn't start for a
Well my car has had a slight issue for a little while now. When letting off the gas the rpm's sometimes stumble and almost stall out. A few times it has actually stalled.
The rpm's have also held around 2-3k even when warm for a little bit when off the gas then came back down to idle.
Today it was fully warmed as I just rove 20 miles and came out of the store and started up fine. Drove a hundred feet or so and at a stop the rpm's dropped too low and it stalled out. I tried starting it but the first couple tries it wouldn't start.
Then it did but rpm's klept dropping kinda low. Didn't stall out again but this has been happening every once in a while now.
During last winter it happened when really cold and stalled out. So it's not just heat bogging. I know that feeling.
Would you think it is a bad MAP sensor? Or a loose one or something? Or maybe the IAC needs to be cleaned or replaced?
There are no CEL's or anything so not sure what to try out first.

Did the MAP wack thing before. Do I have to wack it really hard?
For the IAC I't just bolts right off right? Carb cleaner should be used to clean it out?
What about the MAP zip tie thing? Is it normally lose without that or something?

Alright well got some carb cleaner so gonna clean up the IAC tonight. Hopefully that will help. Wacked the MAP sensor again so I'll see. Throttle cable seems to have tightened itself a little bit some how.There is zero slack in it now so might be why it has stuck a little higher a few times.

Cleaned the IAC out. Man was there a lot of build up in the middle chamber. The little roller thing did not seem to want to rotate freely at first. Once cleaned with the carb cleaner turned easily. I had to use a flat head screw driver to scrape the buildup off the walls. Wacked the MAP and reset the ecu. Took it for a spin and it didn't dip at all. Hopefully it will stay this way. Doesn't always do it so I'll know in the next few days how much it helped.
