Engine Mechanical problem
1990 Dodge Spirit 4 cyl Two Wheel Drive Automatic 88K miles
Took my car to a mechanic due a rough idle situation. He replaced MAP sensor, distributor pickup, spark plugs, and fuel filter, none of which solved the problem. He then somehow raised the factory idle form the correct 750 rpm to 1000+ rpm, which only diminished, but did not solve the problem. I finally figured out the engine needed a new EGR valve. The engine now idles smoothly, but, of course, it has a too high idle speed. How do I lower the idlel speed? Is there some kind of idle speed screw l; iek the older carburetors had? I asked the mechanic, but he told me it was kind of an involved process, and preferred I bring the car back to him and waste more of my hard earned money!
