I switched computers from the 88 ca mass air 5 speed computer to an 89 mass air computer and the purge solenoid fault code went away. Also wired up the FP monitor and that code went away with the engine off all codes are away. I started it up and ran codes first 44,94,and 33 came up tad,tab, and egr not opening. Replaced the EGR. Ran the scan again 33 egr problem went away but now code a 12 code idle problem. The thing is if I don't keep it idling at that range it fluctates quite a bit. It's around 1-1200 rpm. The tab and tad solenoids are installed but aren't doing anything because I didn't install the smog pump. Is there a proper way to eliminate them to erase the codes Also would this be causing a problem with the mixture?
