A friend has recently purchased a new 2005 2500 Diesel with auto xmiss. He is not a member yet. I told him I would ask about his problem for him. He has a problem with the accelerator (throttle) sticking. He has to shut down, coast to the side of the road and wait awhile. Doesn't seem to matter if the engine is hot or cold. Time between occurrences vary but it seems to happen pretty often. Can anyone shed some light on this? Thanks.
