I removed my ac to convert to oba, and it hasnt worked since I owned the thing anyway. I threw a code p0443 (evap purge solenoid). Should I throw this back on or will I be fine? Ive had no driveabilty issues, not running lean or anything. I plugged all the related vaccum lines as well.

 

It's probably a vacuum leak, especially since you messed with the vacuum lines. Smoke test it and see.
