Hi everyone,
I have a John Deere 40 that has been running rough lately and only wants to hit on one cylinder sometimes. So I changed the spark plugs out first and it still did the same thing. But I noticed if you pull the spark plug wire off just a little bit on the number 1 cylinder the tractor runs great, put the spark plug wire back on all the way like it's supposed to be and it drops a cylinder. So the next thing I did was replace the distributor cap and spark plug wires because there was corrosion on both. It still does the same exact thing. You pull the number 1 cylinder spark plug wire off just a little where it's still making spark and it runs great. Any information and help on this would sure be appreciated. Thanks
