i got a 93 dakota 5.2 , stalls when its hot , and is hard to start when hot. I unplugged a vacuum line and it works fine other than ideling rough when its cold. i think it may have somthing to do with the IAC but want a second opinion. thanks

 

The IAC is the usuall cause of Idle problems. Take it off and make sure it can move freely. Clean it up and replace it if you need to. You said its hard to start, have you tried pressing the gas when starting. Does that help or no. If vacuum helpes your engine then the MAP sensor may be your problem.

 

before i unplugged the pcv vacuum line i had to keep the gas pedal down a ways to start it when it was hot
