Passing Emissions

Hey Guys, i need a lil help here, my 94yota wont pass the emissions test. The HC is the only fail.

I have -
- New Plugs+Wires+Cap+Button
- New Head
- New Valves+cam

I have 33's tires
I did find a loose vacume hose on the Pressure Regulator

( Would using stock wheels and tires help PASS??)

Thank You in Advance for any help

I don't think the tire size will make much if any difference.
