resetiing/checking the base CO is easy. Warm it up, place the + lead of your DVEM in pin #3 of the diag socket (round thing on the l/h inner fender near the EZL) ground the other, set it to duty cycle and watch it idle. You should get a reading close to 50% with a 5 tto 10 swing. (depending on the system and speed of your dvom) 3mm allen in the center of the air cleaner is the adjuster, the tower for the adjuster might be plugged. Get creative getting the plug out, towers are cheap if you demolish it, just keep the metal out of the engine)
Personally, I'd get a tech to resset/check this as getting heavyhanded here could get expensive.
