'91 f150 4.9 - Drive cycle?

Just in time for emissions testing I have started getting a flashing check engine light - so weekend projects are on my horizon. Because I'm running out of time now and I never smog early in the month like a smart person, is there a drive cycle I need to do to not give me a hassle at the station?

Find out why the CEL is flashing. That should help you pass inspection.

The smog inspectors probably won't connect anything to the vehicle PCM to check it out.. they only do that with OBD-2 vehicles here in Canada, so as long as your check engine light isn't on you're good to go but that means you have to fix whatever is causing it to flash right now.
