there are 3 codes... po173 fuel stream malfunction (bank 2) po170 fuel trim malfunction (bank 1) and po455 emmission control leak (large) ....someone please tell me this isn't as bad as it sounds...thanks for the help....


BTW...while searching the older threads I do get the general idea that the po170 and po173 codes should get cleared up by replacing the mass air flow sensor but I couldn't find anything about the po455 which specifically addresses the 280 engine....thanks again...
