Hi there. There are a lot of possible issues that can cause this. If this occurred right after the replacement of the alternator then I would check the fuses first. It is possible that a wire got shorted during the installation and may have blown a fuse. If the fuses are fine then I would scan the computer for codes to see what comes up. It sounds like it may have an air flow meter that is not hooked up or possibly another sensor.

A computer scan tool would be needed to check the sensors to make sure they are sending a good signal. If you want to have this looked at, consider contacting a certified mechanic who can come to your home or office to diagnose this stalling issue.
