Idle Problems? Heres Your Cure!
My car used to have a rough idle and "surge" when in drive or park. I changed the fuel filter and no more problems. I went under the car and zapped the filter/lines with liquid wrench(fearing they wouldnt budge) but I was amazed at how easy it was to take off considering that rust was everywhere.
Remember to diconnect battery, and put a pan under the filter because gas goes everywhere!

Changing your fuel filter is one of the many over looked things on any 3rd gen. However, there is far more that can cause a rough idle. Glad yours was a simple fix.
