94 Wagon Failed Cal. Smog!

Hey Forum, my 94 F22B Wagon failed smog. So I changed the oil, plugs, air filter, and added seafoam to gas and crankcase. Any more advice before I pay the smog man again? Here's the 5-gas readout:

Inspect the distributor cap and rotor for signs of wear.

Excessive CO is caused by lack of oxygen (air) to burn fuel completely. Check air filter and air intake for possible blockages. If good, then a new O2 sensor should be considered.

good luck
