OK just bought a 156 TS and when I reach forty five MPH and above, a noise like a propeller driven aircraft engine kicks in, any ideas anyone. Also a very scary thing happened on two occasions, it was as though someone took over the control of my accelerator pedal and smashed it to the floor subsequently had to endure a screaming engine so switched off the ignition, waited five minutes started the car and continued as if nothing happened. Any ideas out there?

the second problem sounds like a throttle body problem. Do you have a cable driven throttle or a fly by wire throttle?

Does the propeller noise change frequency with wheelspeed, engine speed or is it the same frequency at all time?
