Re: DTC codes 16684 and 16687...what are the likely culprits? (Vickers)

Plugs? Wires? Good place to buy either that can overnight them?
Good replacement for the Denso Irridium for forced induction?
Anything?

Replaced the Denso Irridiums with Bosch Super FR6DCX as suggested in the MkIV forum, and that didn't fix it.
Any suggestions?

I know that this is an old post and the owner "Vickers" made his last vortex post on 8th-Jun-2k3. So I don't expect him to reply.
My question is I have a friend who owns a 2K1 Jetta and they have the exact same two (2) DTC's (codes 16684 and 16687).
Can any one else jump in and let me know what corrective actions will resolve this problem.
Is it a coil pack issue?
Thank you for your assistence
