on the passenger side of the engine you will see 2 small metal rods at the top of the engine just below the intake manifold there are little white clips that hold the rods on these clips usually break and the rods come off

I'm assuming you have the 4.2l v6. If this is the case, there are two intake runners per cylinder, one long (torque) one short (horsepower), default setting for these would be long runners or closed.
There is a valve so to speak inside the intake manifold operated by a motor that switches to the short runners when the RPM"s reach a preset point. However there has been a problem with this design, not only with the 4.2's, but the 2.5's and 3.8's and every other motor that uses this design.
The motors go bad, or the valve gets carboned up and no longer moves. If you have a 4.2 start there, if not I'm not sure what is wrong.
Good luck and hope this helps
