hi can anyone tell me how to open the tps on my 1991 318i.m40 motor as i would like to clean tne carbon track, as the car has developed a flat spot.and i suspect this is the problem. i tried once before but broke one of the tabs off
and didnt want to go any further in case i damaged the hole thing. pics would be advantage. thanks .[/i]

There isn't a carbon track, it's a pair of switches.
One switch (the one for throttle closed) is a sealed microswitch, the other (for full throttle) is an open contact that can be cleaned.

Are you confusing the TPS with the AFM (air flow meter)?
