My F250 has been misfiring under load for a while. I only put 2-3000 miles a year since I retired and I admit I've been lax about maintaining it. I replaced a coil three years ago and it acted the way it is now but this time it's worse. The last few weeks since the weather is in the low 30s the first start of the day takes a lot of cranking. Yesterday I took a half wagon load of hay about five miles away and it was really bad. When I got back to the barn the exhaust smelled kind of sulphery. First time for that. Does this sound like an ignition or a fuel problem? I'm thinking ignition, bad smell=unburned gas in the converter.
