1992 300E 3.0 -165 k miles
Following have been replaced : suppressor shield under rotor ,distributor cap and rotor-wires are recent .Lubed linkage and checked cable

Engine will not rev past idle at times, possibly heat related. Initially the car would display this symptom and then perform normally . It is like putting your foot into air the as it does not respond. Never stalls ...once the revs went crazy near red line burning gravel...

Next two guesses are rear Crank angle sensor and coil. Ideas ?
