Hello everybody, so I just recently got a 2000 mustang six cylinder and when I start her in the morning she runs perfect but if I stop at a grocery store and I come back in the car and try to start her she’ll start but have a very low RPM like she’s ready to die and I have to give her gas or she will just die, I’ve read the forums and a lot of people said it could be the crankshaft sensor,I replaced it,and I still have the same issue, any advice would be very much appreciated I hope everybody has a wonderful afternoon

Sounds like it could be the IAC- Intake Air controller. It helps keep your car idling properly.
