Replaced the o2's and cleaned the IAC but no real change. Idle improved marginally but still stumbles from time to time. Car is also almost undriveable in the rain/real high humidity. It'll shudder under low throttle situations... ignition related? Cap/rotor look nice enough and plugs/wires are new. MAF is also on my list to clean, just such a pain in the ass to pull it on this car..

Spray electronic cleaner under cap and see if it improves when dry? Sounds like an old school moisture problem. Small crack in underside of distributor housing maybe???
