94 Automatic 318is
I just got my car back from this shady ass mechanic whom I paid to supposedly fix ignition coils and oxygen sensor (air flow meter) on my car. Before I brought it in my AC had NO problems but now he says when it's idle the RPM keeps revving up and when it gets put to 2 fan power the engine just shuts off. WTF. I tested this when I got my car back and it NEVER did this before. I'm positive. I didn't pay him cus he thinks i'm gonna pay him on Monday but what could be causing this?? I know he must have done something wrong.
BTW, I'm the one who's been shafted at the car wash for the damage, etc.
