Fault code help needed
Hi, I had the check engine light come on while on the freeway. When I checked via my Durametric it came up with 2 codes: P0420 and P0430 Both say "Short to B+/upper limit/rich mixture Threshold"
Any idea's on how I solve the problem will be greatly appreciated as I haven't a clue as to where to start looking to solve the problem/s.
thanks
Larry
