On the chevy v6 engines it real comon to have intake leaks.I would try spraing carb cleaner around the intake while the car is running and see if it changes the way it runs.If it does that is your problem.If the intake has a leak it will **** extra air in and cause a missfire.

Won't idle, runs rough under throttle


Check all of your tune-up parts. (Distributor Cap, Distributor Rotor, Spark Plugs and Spark Plug Wires) Also perform a compression test if no problem is found with the tune-up parts. Check also for vacuum leaks and the Intake Air Control Valve (IAC) for the "won't idle" problem.

mcdevito75 here, Sounds like a faulty voltage regulator, it"s 1 unit with the alternator, change the alternator, also the alt. supplies juice to the ignition switch, distributor abd plugs, thus a rough idle due to bad alternator.

IAC motor


OBD does not control, an idle logic circuit does, Disconnect the battery and let it relearn idle speed, it has fuzzy logic capability, so it learns your driving habits.
