Thread: stalling when let go of gas pedal!

LIM was not swapped over by me. i believe its a leak through the pcv valve, as the engine was standing on its side when i picked it up -.-

Give the PCV valve a check and make sure you have 2 o-rings, one actually on the PCV itself, and the large one that sits in the lip of the UIM that is covered by the cap that holds the MAP sensor. Been there, done that lol..
