What is the TOYOTA recommended (if any) schedule for replacement of the spark plug wires, the rotor, and the capacitor?
___________________________________________________________________________
Dealership wanted to replace plug wires, rotor, and capcitor on my V6, which now has 60,492 miles.
The NYState emissions test was not passed on FRIday. Replacement of the original spark plugs and PCV, and the air filter was done yesterday. The CO went from 51.75gpm to 0.2; the HC went from 1.44 gpm to 0.03; the NOx went from 0.13gpm to 0.81.
Thoughts ?
