Rough idle when warm - suggestions? 200 1990


Recently, my car has developed a rough idle only when warm. It is okay cold. Car runs well otherwise.

The lowdown is that the car is long overdue for a tune-up. New plugs, wires, cap and rotor will done as soon as I have the time. The flame trap and all its hoses etc. are also overdue for a good reaming :)

My guess is a bad plug or wire. However, someone in the archives mentioned the RPM sensor. Assuming my 90 has one (I think so...), it is original and probably should be checked.

Any other ideas - fellow BB'ers??


Thanks,
Jim
