Rough Idle at cold start
When I start the truck up in the morning, it idles up like it should, then drops drastically to below 500 RPM, runs rough, and will kill if left alone. What I do is start it, then give it some gas (about 1500 RPM) for 5-30 seconds until the engine smooths out, then I let off the gas and it idles fine from there on out. This only happens when the engine is cold, and has not been started for over 6 hours. Any ideas as to what this may be? I'm thinking TPS, but am not sure.
Thanks,
Mike
