Re: 02 Passat V6 4 Motion - - - low speed missing
I read on another Forum about this vacuum operated valve sticking, the one located right beneath the coil pack. Checked mine and yes it seemed to be stiff to move too. Lubricated that so it rotates smoothly. I wonder if that was the cause of the misfire.
Haven't had a chance to properly road test yet, so we will see if it is cured.
What is the purpose of this valve, and how would it affect engine tuning ?
