Clean the inside of the throtle body where the butterfly is. Also clean the idle speed control which is on the side of the throtle body. Good luck. 11/11/04 - just happened to me. My mechanic is going to; 1) replace EGR valve He also found a leak (with a special leak detecting gadget) at the intake manifold, so that gasket is being replaced. Check your pcv valve, this on thing can cause a lot of troubleshooting. Only 3-5 dollars to buy.
