super rich causing two dead cylinders......

ok guys, hydro locked

we have had knarly rains for the past 4 days, i was on my way home and inded up going through 6 inches of water, it was down the street from my house, and it stalled, i fired it back up, ran fine kept on shoving at about 1200 rpm and 4mph, stalled again, hydro locked

i watched the rpms slowly drop from 1200 to 0, was not a quick stall it was slow

i pushed it home and pulled all the plugs out and cranked it over a few times, cleaned the plugs and fired it back up, runs super rich

i put some new plugs in cuz i figure the old ones were fouled and still runs rough, did compresion test, all is good, so i figured ou two cylinders are not firing, it also hapens to be the two cylinders that had water in them, only about a spoon full of water came out when i cleaned out the cyclinders.

i also have a cool air intake and were my air intake temp sensor is located , it got water logged,

i pulled it out and water poured out of the sensor
im also thinken the oxigen sensor could be fouled also , all the cylinders are runing rich, only two are not firing, and im looking for other opinions

Re: super rich causing two dead cylinders......

Well, definately get that sensor dried out. O2 sensor, not sure if water would mess one of those up, anybody else know? Since you replaced your spark plugs, make sure the gaps on the two cylinders that aren't firing are correct. If they are, then check if the spark is getting through the spark plug wire. Out of curiousity, what were the results of your compression test?
