Hello, I wanted to see if anyone could help me with my code issues... my check engine light has come on . I had it checked at autozone , and the codes are: P1351, and P0420 .. I was told that the 1351 code was the problem, and making the other code pop up... so, my question is, is this a coil problem or a module problem.. the code sayed something about a voltage of 4.6 ..... which I have no clue about...... Please Help........ thank you very much....
