I have been trying to figure this out for longer than i care to admit. I am working on 4 cylinder gas engine with firing order of 1342. #2 and 3 cylinders will not fire correctly. I had always assumed it was my distributor but today I took the the #1 wire and held next to all plugs and 1 & 4 jumped a nice strong spark and 2 & 3 had very weak spark. did the same with the #2 wire with same result. and the did same with #3 wire with same result. Ok, I then put a new plug in the #3 hole and tried again with the same result. I feel that i ruled out a faulty distributor as three different wires/lobes/rotor positions give me the same result with weak spark on 2 and 3 cylinders. I also feel that since i tried a new plug it cannot be fouled plugs. I am not sure how its possible but its like the plug is not grounded while screwed into the head. I am out of ideas. My next plan is to take off carb and burn out cylinder- put all new plugs in and try same again, in case it does have something do with fouled plugs. any suggestions ??? thanks norm
