Anyone know why a 97' CL420 would just switch itself when ticking over stationary, or when coasting up to junctions?
Very intermittent, never happens when bombing along using the gas, only coasting, or idling.
Snap on scanner indicated issues with throttle body potentiometer and air mass sensor but not convinced.
Took off throttle body to clean butterfly and now have rough/erratic idle problem (gasket sound no vacuum leak).
When disconnecting the Air mass sensor while engine is running it does not affect the running of the vehicle and does not switch on the Engine Management Light?
Seems odd.
Any pointers would be most appreciated.
Thanks
Rob
