Computer problem
1997 Mercury Tracer 4 cyl Front Wheel Drive Automatic 173000 miles

I have a code that states insufficent egr flow. There is no vacuum leak and the engine performs flawlessly. What is the chance that the egr valve is the defective part on this car. I removed the valve and cleaned it w carb cleaner. How do I reset the check engine light and if not the egr valve what else could it be?
