RudeMom Posted August 2, 2022 Share Posted August 2, 2022 When idling or coming to a stop, engine will stall. Starts right back up with no issue. Only does it when AC is on. Does it in gear or neutral. I’ve cleaned the throttle body and MAF, checked for vacuum leaks and found none. 0 Quote Link to comment Share on other sites More sharing options...
robinsone Posted August 10, 2022 Share Posted August 10, 2022 I believe there was a recall on the throttle bodies. I had mine replaced for free, maybe check that. 0 Quote Link to comment Share on other sites More sharing options...
Javier Posted July 6, 2023 Share Posted July 6, 2023 My 2011 2.5 fusion is having this same issue. When in open loop it runs fine, as soon the pcm takes control, the engine starts to run rough and then if you put it in gear or turn on the a/c, it stalls! There is no vacuum leaks, no misfires! Have anyone found the culprit for this issue??? 0 Quote Link to comment Share on other sites More sharing options...
WKelley Posted July 6, 2023 Share Posted July 6, 2023 I'm not sure how to test it, but my car had random stalling issues and needed a new fuel pump driver module (fancy relay). I threw a lot of money at it including a $400 fuel pump. Not sure if this is your issue, but if the stalling seems to be getting worse this would be a good place to start. 0 Quote Link to comment Share on other sites More sharing options...
