Hello Everyone! I was wondering if I could get some help figuring out what is wrong with my Accord! PLEASE!!! I went and had my car scanned at auto zone and they gave me codes P1456,1457 and p1399. What my car is doing though is when I put it in reverse and press the gas it will sputter and then die. Sometes it will do it in D4 right after shifting from reverse. I've changed the spark plugs and fuel pump which a guy at auto zone told me it could be. But it's still doing it and I'm out 200$ lol. Please if anyone has any idea of what it could be it would be greatly appreciated! Thanks , Kelly!
