Assuming a 3.3l engine [ I believe the 3.8l is same], replacing the EGR Valve is a piece of cake. This "valve" is the cylindrical-looking gismo just above the alternator on the left side of the engine as you face the motor from the front. It should cost around $70 at your local parts shop, and come with the gaskets. Replacing this part should be intuitive if you are somewhat mechanically inclined, and take less than one hour. Caution: wear gloves to prevent burns if the engine is hot. Four steps:
1. Disconnect the wire harness: Push the red plastic retainer to the right and wiggle the harness until completely loose. 2. Take off the two bolts holding the top pipe [8mm, I believe]. 3. Take off the two bolts holding the unit to the manifold [10mm]. The unit will be free after this step. Replace the unit and gaskets and bolt it on. Replace the wiring harness and you have it. The "Engine Light" will not automatically reset. You have to do this yourself if you have the tools, or have it done. Yes you can..
