So I found this forum when looking up how to manually check my check engine light, thanks guys
But now I found it's throwing codes 51 and 34. Knock sensor and Injector circuit.
Where do i go from here? The car runs rough when the light comes on, but fine otherwise. I have rebuilt fuel injectors, like 6 months old.
Is the knock sensor going off because of an injector problem? Or is the knock sensor broken and need to be replaced?
Please i could really use some advice, this is my only car and i'm lost without it
