So I just waxed my 300SE (1991, M104.990 722.368 trans) and wanted to go for a cruise and guess what - pressed the gas and nothing happens. Car is just rolling in DRIVE and no response from throttle pedal. Got back home imidetly. Put it N, the same. If you pressed the pedal really hard it went slowly up to 1.5K RPM. Switched the car off, restarted, revs up like it should.
What could be the fault, where I should look now?
P.S. after buying car, took it to mechanic. He said wiring has been done and engine and all the components are good...
