Thanks Saumil for the suggestion. The first post I read about a throttle swith going bad seemed to highlight my problem. When I disconnected my idle control valve to keep my rpms up in an attempt to prevent stalling, I felt a distinct engine braking as soon as I removed my foot from the accelerator when i was doing 60 mph down the highway. Does anyone know if this is expected behavior if Im driving without the idle contorl valve connected or does this point to a bad throttle switch?
