I can give you a generic drive cycle. I don't know anything about Oregon emission laws.
Cold start, temp less than 122 degrees F.
Idle 2.5 minutes in drive, (auto), neutral, (man) ac and rear defogger on.
Ac off, accelerate to 55 mph, 1/2 throttle.
3 minutes of steady state driving at 55 mph.
Clutch engaged, (man), no braking, decelerate to 20 mph.
Accelerate to 50--60 mph at 3/4 throttle.
5 minutes at of steady state cruise at 55--60 mph.
Decelerate, no breaking, end of drive cycle.
