Discuss the causes and fixes for P1311 Isuzu OBDII Code
-
I changed my spark plugs with some NGK and now i get this code along with p0300 and my check engine light blinks when i accelerate? can this be cause by spark plugs?
-
Yes, it's possible. If the light is blinking, it means that one of the cylinders is not firing. Start by checking all the connections and make sure you are using the correct spark plugs as well.
