2008 Chrysler Sebring Touring, rpm's dropping, rough idling, etc Sign In

Chrysler Sebring Touring
Engine size-2.7 (I think)
157,000ish km

First off, thank you for reading! Secondly, my understanding of cars is little to none haha so please forgive the lack of knowledge.

So I bought a used '08 Chrysler Sebring about a month and a half ago.
It was running fine, all was well until I was in my driveway, had the car in park when the car had a bit of a shudder, the rpms dropped and then it revved high, sort of like it was preventing itself from stalling. I didn't think much of it.
A week later maybe I was at red light, it was raining pretty hard when it did the same thing. Rpm's dropped, car shuddered then revved high. Not even 5 minutes after that, the car stalled in a parking lot, all the lights came on. It turned back on right away and then nothing else happened for a week or two. It should be noted that the weather was dry for that time period.
So it has sporadically been doing that, rpm's drop, rev back up high and shudders. Occasionally the rpm's will just drop, car stalls but no lights or anything come on. It always starts back up fine, no wait time.
I find that it happens most often when it's wet, raining and snowing however it has happened on dry days and not always on wet days.
About 4 days ago (it was day 2 of snowy weather, the first day brought no incidents), it was doing the rpm thing but this time when it stalled at a stop sign, the check engine light and another light that looks like a lightning bolt (apparently it's the electronic throttle control light) came on but they went out and didn't come back on. Then today I put some fuel injector cleaner in and after putting my gas cap back on and turning the car on, it said gas cap on the digital screen. Turned car off, turned it back on maybe 30 minutes later and it no longer said gas cap but the check engine light is now on. Not sure if those things are related at all but just some background info.
The car only has these issues when idling. It runs beautifully whilst driving and is a great car minus this frustrating issue. When it first happened I brought it to the mechanic I purchased it from. He used his code checker thing, said nothing was coming up, looked under the hood, said everything looked fine, and then said unless it's happening all the time or does it for him (which they never do!) then there isn't much he can do.

Apologies for the novel but I figured I'd provide as much info as possible. Thank you again for reading and any suggestions!

You really said it all that you know NOTHING about cars so with check engine light on there's info for a pro shop to go on and fix this. Not much is as simple as a gas cap or adding a can of magic in a can to the fuel.
Untold # of issues yet to be found. Too late but when buying a used car have it fully checked out pre-purchase and contingent on what is found THEN negotiate or walk - not after the fact.
You probably don't have a maintenance or accident history so now time to find out as much as you can about what you have and make the history without an accident please.
IDK - any chance of a warranty still from seller?
It's a USED car - anything possible in this short of time at least find out what you have and what it will take to put it in order. No screen telling you what's wrong like the gas cap episode is going to do it for you,

Well, that should fix everything. See if they have a can that fixes check engine lights too.

If you decide to give up on the "Mechanic in a can", have the codes read and find outs what's really wrong with it.
