Well picked up the damn thing and once it gets to about 750rpm it’ll surge to 1100 or so rpmi at park or in gear. Was coasting to a red light Nd it surged. That unexpected acceleration scared me! Doesn’t surge at 3k plus rpm anymore.
So back at the shop it is.... /sigh.

There may be a "relearn procedure" . If a relearn is necessary, and you ignore the relearn procedure, the car will eventually figure it out in about 1/2 hour.
How long was your ride? . They could have left a vacuum line off. Or it fell off. But I'd ask them is a relearn is necessary.
I replaced a Crank Position Sensor to alleviate stalling on one of my cars, (sucessfully) and the relearn was not necessary.
But when I replaced a gas pedal on another, I had to sit in the driveway with the car running and put the car at different revs for specified periods.
When I got my TCM (transmission control module) flashed by the dealer. I picked the car up and it bucked like a bronco. The next day I performed the TCM relearn procedure. Car needed to relearn the shift points. Drive 75, slow down to 45. Up to 75 , slow to 25, etc. Not suggested to perform during rush hour.

I pulled it out of the dealership and went probably 1/10 of a mile down the road when I coasted to the red light and it surged on me. So I pulled into the Taco Bell I was nearby and parked it in a space and left it in idle and watch the needke slowly go down and then back up every 5 to 10 seconds it seemed. They mentioned they test drove for 20 miles at least without any issue

No lights came on. It would not stall it would just bounce up in RPMs a little bit then slowly come back down and bounce again then come back down over and over. Either way it’s back at the dealer now for them to double check.
I hate when people waste my time and money when I get a phone call that says it is all fixed and that they test drove it ya know... Service manager will get a call tomorrow on this kind of sloppy work follow through. So stressful.

So they claim to not found anything with the car today, and said they were idle for a a while. The service manager is going to take it out for a test run tomorrow morning and then I will come back to pick it up to see if they’re full of crap or not lol
The service advisor said the RPMs would go up when they turned on the air conditioning and that was it

Well, Thursday it acted like the engine was trying to stall and the computer was adjusting for that.
If I'm following this story correctly... before the crank sensor was replaced, it couldn't do that too well.
Maybe it was just "learning'. . If it continues ... like I say, there's shit you can check.
Ya know, before you drive the thing off a cliff.

Hey @Bondo 440 Have any experience getting a car out of limp home mode?
Buddy has an 04 Lexus gs430, accidentally connected the battery backwards and blew the ALT main fuse.
Would start but wouldn't go in gear and no lights or instruments would work.
Got the shift override figured out, have the fuse bridged, so the lights and gages are working, but it has no power and won't Rev..... Hopefully the ecm isn't fried, really just trying to help him get home at this point.

Check under hood fuses. Look for anything with BCM as well. Fuses will be visually blown if bad,.
You need to know if you still have 14 to 11.5 VDC on the batt. Under that, the BCM and ECU shut down.
You can Jump his battery that will keep the computer running for a short while.
For the time being, shut off all accessories and pull the relay for DRL so the headlights don't draw you down.
I'm searching now and I know what I'm looking for so stand by,

Has a fresh battery on it, and the alternator seems to be working with the ALT main bus fuse bridged, but there's some kind of clicking in a relay in the other fuse box and something is causing bad readings and various error lights to show, vsc, batt, check engine, etc...
Can you identify which relay is clicking ?
This was before I read your second post--
I'm thinking of TPS the throttle position sensor. Most cars have a "relearn" procedure I've mentioned to Bostoneo in the past, but this vehicle all I can find is one guy says turn the ignition key up to accy without summoning the starter, then back to off ... about 50 times.
Another recommendation is either leave the car off for 20 minutes with the battery negative terminal disconnected. Then put it back on and retry.

And pull the relay for the DRL. It's tagged in the fusebox under the hood. You could have melted the insulation on your headlight bus.
It would be enough to flutter the car. The negative pole of the battery has one path that goes directly to the headlights. Hot power there could cause this condition.
Pull the Daylight Running Light relay and see if the clicking stops
