Re: TFI module
you got to take the dizzy out to get to it, its the same position as my XF. You can't get a normal screwdriver in, but I doubt you would find a bent screwdriver, unless you bend one yourself.
I just marked the distributer with white out so I could take it out, and then put it back in and line the whiteout marks up, that way you dont mess the firing up. Took me 10 mins to do, and I am not the best at mechanics.
