I powerwashed my engine last week with the result of having it run,
seemingly, on less than 4 cylinders, sometimes "kick in" and run ok.
checked all the plugs, all looked the same tan colour, cleaned and
dried the inside of distributor, pulled and cleaned all electrical
connections I could reach, including O2 sensor... one connection
looked sketchy, that was the hall sensor at distributor. the rubber
boot fell apart in my hands.

All connections that I was able to, I abraded with #400 silicon
carbide paper then put back together with  silicone grease. It seemed
to have solved the problem.
