Well, we just swapped my old ZC into my friend's EF. When I had it, it was running code 4 and 16 (fuel injection and crank angle). Now it is running a code 9, which is cylinder 1. Does anyone know why this happened, and how it can be fixed? Thanks.

 

a guy just posted on herer about a code 9 and i gave him a few steps to start to see what is wrong, try follow those and just post up in that thread

 

its #1 cyl position sensor.. if its sohc you will probably need to replace the dizzy, if its dohc its a sensor on one of the cams
