Hey guys when i have my a/c running while im sitting at a light and then i turn my a/c off, the car stumbles pretty bad. It goes away though if i put the car into neutral and then back into drive. My volts also drop pretty low during this and while im making low speed turns in like a parking lot. Any suggestions....battery...alternator .....help

 

Have the battery load tested, if the batt is good then check voltage at the battery with the car running, should be around 13.8~14.2... If not then its the alternator.. Or it could me the IAC.... Also, check for vacuum leaks...

 

AutoZone does this testing right?

 

ttt...I just got the battery and alternator tested and they both were good.

 

check ur compresser out maybe its going south ? and causing the problems
