P1404 Exhaust Gas Recirculation (EGR) Valve Pintle Stuck Open P0404 Exhaust Gas Recirculation Circuit Range/Performance
V6 3.8L Spitting out the above codes.. There was also another code that was since erased regarding something to do with a solenoid (real specific, I know).
I had been reading somewhere that solenoid degradation could affect the performance of the EGR valve.
My question is basically this:
While I could simply clean the valve as a possible low-cost fix (my vehicle has a HORRIBLE rough idle at times), is it possible that there is a problem with the solenoid; which in turn affects the EGR valve; which in turn fills up the cabin with rancid smoke?
