So I’m starting to see my RPM’s fluctuating from 400-750 both on cold start and after driving for a while. Not sure what’s going on but doesn’t make a difference if I’ve driven it for an hour or just turn it on. It keeps fluctuating and causing the car to shake when I’m sitting at a stop. I’m at 60,000 km which is roughly 37,000 miles. The only thing I’ve done to the car is downpipes and akrapovic exhaust but I’ve had these on for the past 3 years with no issues so I’m doubtful that it has anything to do with the downpipes. I’ve set up a service appointment at my local dealer but they don’t have room until April 11th to see me and thought I would ask some of you guys to chime in. Any help would be appreciated. Thanks in advance.
