Unhappy John Lay

1977 350 SL. When slow running the rpm continually hunt until eventually it stalls. Have tried changing everything but so far no change. Can anybody throw any light that might point me in the right direction.

If the idle hunts, it sounds like you have a vacuum leak somewhere. Not helpful I know, but at least a place to start.

Did this happen suddenly, or was it a graceful degredation?

Did you change the rubber seals between the intake halves?

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant
