Volks,

I'm having a rough idle problem with my = Syncro 16" Double-Cab with the US spec 2.1L "MV" wbx motor.

Currently it has no O2 sensor hooked = up.

Would that make much of a difference in the idle = smoothness?

Any tips on things to look for that affect = the quality of the idle smoothness?

New plugs, cap,rotor as well as a new fuel = filter, have been installed.

Any and all suggestions are gratefully appreciated.

Cheers

Glen
