I have an FE9 truck. I have the egr blocked and have run with the egr plugged in and unplugged. My truck sets codes, but no CEL. I had it checked with the Tech 2. I have a fingerstick sitting in my toolchest. I got it just in case I set the light. I have not noticed any performance changes, so the stick will remain in the tool chest just in case!
I have a FE9 truck... blocked the EGR... and I get codes and a CEL. I've tried clearing the codes and running with the EGR plugged and un-plugged and no dice. Have a Fingerstick and will install first chance I get. Who knows?
