so i picked up another da and got a few codes 12 and 43 if im not mistaken 43 is something about fuel delivery and after searching i found that a tune up will make it go away, but code 12 is the egr system, (thats what it says in the teg tips) and i dont know how to go about fixing that. Has anyone here ever gotten code 12 and was there some way to remedy it by maybe cleaning the egr valve, what can i do to make it go away
If it is indeed the EGR system you probably have a cracked/plugged vacuum line or a bad PCV/Charcoal Canister. Check all of your vacuum lines.
