RPM up & down
 

I have an E320 Wagon and lately the throttle is ramping up and down. It is especially noticeable when stopped but I can feel it even when driving. It has been suggest that the MAF sensor is shot but wanted to know what anyone else thought???

Maybe the throttle control module?? I hope so re. less expensive and maybe replaceable myself?

Thanks for the help!

More likely to be the throttle assy than the controller.
