high idle after upper intake manifold replacement
My 1997 park avenue idles high after I replaced the upper intake manifold when it failed and leaked coolant into the intake. The service engine soon light is on, the code was something about idle air control. The MAF sensor has been replaced because we broke the old one while removing it from the old manifold.
The engine is the stock GM 3800 non supercharged.
All help is appreciated.
