They sit inside the rocker cover garnish and have been known to go missing, when under full throttle the coils can jump off the plugs Link to comment https://www.fordxr6turbo.com/forum/topic/49718-running-out-of-ideas/#findComment-733721 Share on other sites More sharing options...

It has solid lines and they can be a pain to undo, especially when its close to the ground. Failing that, I would be looking towards the fuel pump itself, that's another posibility Link to comment https://www.fordxr6turbo.com/forum/topic/49718-running-out-of-ideas/#findComment-733739 Share on other sites More sharing options...
