I don't know the codes. a MAF shouldn't cause problems with the EGR. If it's EGR flow, then it's a sticky valve.rtrejo77 said:Would a dirty MAF really make the code come up EGR flow insufficient? Is it just a guess or how sure are you.
did you disconnect the battery?rtrejo77 said:The car runns fine and I just had the EGR valve replaced a day ago because I thought it might be a sticky valve. It used to read both insufficient and exessive flow but now with the new valve it just reads insufficient
Before you go any further, disconnect the battery for a few minutes and reconnect to see if it comes up again.rtrejo77 said:No I erased the codes with an OBD II
