2001 passat 1.8 coil pack help
Just bought four new coil packs for the car and the coil packs have 2 screw
holes to mount to block. Original version just popped in and fit snug.
The block has the hole bored but does anyone know what exact size I need to get them firmly installed. The car has been a nightmare, rough idle barely drives
without rough ride and bucking. Changed plugs, fuel filter, cleaned throttle body and last chance before sending to dealer is trying new coil packs from what I've read. Reading codes PO300,301,302,304 and PO171. Changing coils make sense with these readings?
