So aside from the fact that im 2 weeks over due:

There is a slight misfire at idle, i've tried plenty of stuff to fix to no avail.
Ive got a new coil on the bench, i dont know if that would help.
HELP! Sad

So heres what i did tonight.
Replaced coil. Opened the bypass screw 3 turns (its running rich). Checked all the wiring again at the harness. One injector at 21.3 ohm, all others okay.

What would a 'VW fix-it' (the pigtail between the AFM and the AFM plug) do on digijet? Im guessing nothing.

I know digijet isnt a huge mystery, but what the fack am i missing? Rolling Eyes I'll see how this rigamarole goes tomorrow.
