Car lurches/shakes at idle?

BKV122 · 07-02-2012, 11:15 AM

GOt a question guys my moms 325 lurches forward or shakes at idle when just standing still, the rpm gauge goes up a little bit. Kind of like a misfire but no codes or service lights. She always puts 92 octane in it. BMW attempted to fix under warranty but still happens and now with the A/C on its more often and more aggressively lurches.
Im thinking maybe a coil is going bad but why wouldnt it show a code?
Any help or ideas are appreciated. Thanks

Since Bmw attempted to fix it under warranty and failed then take it back to them. Why spend $$$$?
