Hey Guys, I was the proud owner of a 2001 beetle. One day on the highway it felt like it dropped a cylinder made it home but it was guttless. It will idle great and rev to 2000 rpm then it bogs and starts to die. Code said random missfire on number 4. changed plugs, then plugwires then coil pack, then fuel pump. Still wont run....Same code same crap. I.ve run out of money and ideas. Can some one help me out??? Thanks. Darcy.
