A vacuum leak might be the cause. Check the large hose from the brake booster to the engine.
Definitely check for a vacuum leak. Which engine is under the hood? If it is the 3800, a vacuum leak is definitely the most likely cause. If one of the smaller engines, I would suspect an intake manifold gasket leak. If there are no vacuum leaks, I would check out the throttle position sensor and crank position sensor. Either one can cause these symptoms as well.
its a 3.1 v6 i believe..
turned out to be a tps problem. not sure what that is but its all fixed now, it made it easy to find once the engine light came on.
TPS is your Throttle Position Sensor. It was misreading the throttle opening.
I have a 1994 oldsmobile ceria cutless S and I changed the map sensor , Tps sensor, also the idle air flow valve and it's still idling high
