Well beleive it,I drove this car back n forth from arizona,to nevada, to California for years . Never had one issue,so if this problem had been happening the whole time i would definitely beleive it to be the o2 sensors,then i wouldn't be on here asking for advice

called wire dryer it's some kind of silicone lubricant but wd 40 works well since wd stands for water displacement,them distributors are terrible for drawing moisture,given you're still running a stock distributor, the thermostat housings like to leak and they're right next to the distributor which is where your moisture would be coming from,just spray it down real good don't be shy with it spray it all down in it under the rotor and on the top of the inside of the cap
