Often when I go through deep puddles I get an occasional misfire that eventually goes away on the interstate ride home. Sunday we went driving around town to see the flooding and high tides from Cristobal. After I drove through some puddles over the paved road at like 30-40 MPH, it started missing like it usually does. But it didn't go away.
Yesterday (Monday), it was still missing. Same with today. I'm starting to get nervous.
I am trying to figure out which cylinder is missing. You can really only get to #1 and #6 easily with the laser thermometer. I can shoot the laser thermometer through the carb heat shield to #2 and #5. #1 is quite hot, like 300+F. #2 is 280-ish, #5 is 260-ish. #6 is 150-160. No clue on #3 and $#4. Swapped out the #6 spark plug wire. No change. Swapped out the coil wire. No change. I opened the distributor cap, no signs of moisture. I have a spare cap and button, so I changed them. No change, still missing.
I suppose pulling all the plugs is next. Not sure what I am looking for besides a wet plug. Plugs were changed 4000 miles ago, along with the wires that broke when I pulled the plugs, about half. Is it normal for #6 to be colder than the others?
Any advice is appreciated.
