I sprayed my valvecover with some Simple Green then scrubbed it with a small plastic brush then I hosed it down. I couldn't get it to start afterward. I noticed there was a lot of water down insde the spark plug holes, so I tried stuffing a rag down in there to get some of the water out. I got the car to run, but just barely. It would idle ok, but when I gave it any gas in gear it would sputter and shake badly. I removed the distributor cap and wiped out any moisture I saw then sprayed a bit of wd40 in there, I then took the wires off the cap and sprayed them with wd40 then put them back on and it hasn't seemed to make a difference. ARGHH!! What should I check now?
