1995 Buick Skylark service engine light

I have replace the egr valve, catalatic converter, cleaned throttle body and service engine light will still come on after running for a while. When put back on scan it comes up EGR problems 3--which is how many times light had come on in between. Car runs GREAT but this light is driving me crazy--any ideas??

Welcome to AF. And the code is exactly and the engine is ? No numbers in the code relate to the number of failures, BTW.

If you're near an AAMCO dealer they'll figure out your engine codes for free. It might just be a sensor since the car runs great.
