Throwing code 32 and I have no clue on where to start. It comes on after ~15 minutes of the engine being on. If I turn the car off then back on, it goes away for another ~15 min. My gas mileage has gone to hell also... Close to 4mpg less than before this code.

 

bah its probably due to my exhaust system being less restrictive. no more backpressure. but what do i do about the EGR to maintain gas mileage?

 

Have you recently changed the EGR valve? The reason I'm asking is because there are three types of EGR valve with the same P/N but a different end designator. (N) for negative back pressure, (P) for positive back pressure, and (blank) for ported back pressure. Our cars use the negative back pressure (N) EGR valves.
