sounds like a bad starter solenoid switch or a fusible link most likely a bad starter solenoid

Did he check the oil? Is it low. It could have a big leak.

Hello. Welcome to FixYa. Please allow me to assist you.
Most likely, your car's computer has 'lost' its basic idle parameters. This can happen when the battery goes dead, the battery is replaced, or the battery cables are removed from the battery.
The good news here is that there is nothing really wrong.
All you need to do is drive the car, hit passing gear a few times, pull off, let it idle, do some start-stop driving, and withing 10 miles the idle parameters will be reset
We have to do this drive-cycle every time we disconnect or change a battery in our shop..
Thanks for choosing FixYa for assistance today.

you most likely need a new alternator

cam shaft sensor

oil pump might be going bad

The throttle body needs cleaning. It has some carbon build up, and when the battery went dead the computer lost its learned values, one of which is base throttle position. Now its reset back to factory specs, not accounting for a dirty throttle body. Seen it a million times

As far as the guage issue it is most likely a problem with the body control module, have a trouble code test run on the BCM to determine the issue, the stalling is caused by the loss of the idle strategy learning when the battery went dead, the best thing to do is the following procedure I use to clear this issue.

Here is the most common cause of surges and stalls (or very low idle) near or at idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
