So here is the story.... A few months ago my 04 1500 had the CEL come on, pulled the code and it was EGR related (P0406 - circuit high). I replaced my valve hoping it would fix the problem, and it did, sort of. The light went off for a while but eventually came back on again for egr, this time code p0404 - Circuit Range/Performance. Now it will go off and come back on as it pleases. I haven't noticed any kind of issues with performance or abnormal noises i just don't like the light. I've been told it may be a vacuum leak somewhere but they are not sure. Have any of you had this issue or maybe know how to go about fixing it? Been thinking about a block-off plate and tune the code out but i need my tuner first :waytogo:
