My 2015 XF has a rough idle at a stop when the A/C is running any one else have this issue?? Has any one ever used over the counter fuel injector cleaner??

 

You give no information as to your engine. If a 6 or (God forbid) a 4 or (even worse) a Diesel then your vibration is normal. If direct injected (as most are) the injection cleaner will do virtually nothing except dry the gas if a little water got into it.

 

Sorry it's the supercharged 3.0 V6
