EGR issues, please advise
My engine recently threw a P0405 EGR valve code. I replaced the EGR valve, cleared the code and all seemed OK till the next morning when it threw the same code again. I replaced the MAF sensor to see if it would help but I keep getting the code. Engine has been running well before and after the replacement. What else should I try or look for?
