Very Rough Idle and Stalling With Any Elec Draw
2006 M6. K&N intake and SLP LMII axelback.
Issue is, when you first fire the car up, it idles very rough and sometimes stalls. If you use anything that draws significant power, you can hear the engine bog down and almost stall. Windows, blower fan. Radio doesn't seem to affect it. Once you start driving, it doesn't seem to have full power, and runs rough. Have to feather the gas while stopped or it stalls. It is at the dealer right now, as it is still under warranty. They replaced an O2 sensor and the Mass airflow sensor. Hasn't fixed a damn thing. Anyone experience this issue? Any ideas?
