I had a diagnostic test ran on my 02 Ford Windstar, It showed that my oxygen sensor and egr valve were bad. I replaced them both, and then took the battery cables off to turn off the engine light. The light came back on, so I had another diagnostics ran,
this time it read egr valve insuficent flow. What should I do now, is it harmful to may engine. Im sure it's carbon build up in the pipe. Please let me know. Thanks, Kevin

Yep! Pull the egr off, clean the port under it all the way to the throttle plate, I use a length of steel coathanger. Put it all back together, reset the codes, if light comes on again, replace the EGR position sensor, thats the one the two small hoses from the exhaust plug into!
This is for a P0401 code, BTW you can't reset the codes that way anymore, reset the light with a scan tool!
