I am trying get answers to " rough idle" on a 1996 oldsmobile bravada
i have changed out the idle control sensor and that helped a little, I have put a complete tune-up except ignition coil, will changing out the throttle control sensor and the pick up coil help eliminate this problem, I also replaced the battery and air filter.
Also what about replacing the oxygen sensors?
thanks for your help!

What is the problem? Also, the MAP is a manifold absolute pressure sensor.

Daniel: Before replacing everything, has the check engine light come on? Also, have you checked for vacuum leaks?

NOTE: All of the things you mentioned could fix the problem, but the parts could still be good.

Let me know about the check engine light.
