Why does cylinder 4 always misfire on a 1998 F150?
Need more information (such as engine size) to tell you why. Experience is anyone of them can misfire but Fords of that vintage sometimes have problems with cooling leaks on that hole from heater hose I had exact same problem on my '99. Leak on #4 plug caused damage to the coil. Changed hose and coil. Coil very easy to replace. My brothers 98 F150 had the same problem, had to change the intake gaskets. All four corners of the intake was leaking. Took about 4 hours to repair. His was a 4.6 motor.

The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

How can I tell which code scanner to use in my 95 Silverado OBD-I or OBD-II?
OBD-1. 1995 was a changeover year. All 1995 cars/trucks (GM to my knowledge, I don't know about the other brands) were OBD-1 and some have an OBD-2 connector, but still are OBD-1.
Mine did the same thing it began to putter in the first few minutes of driving it. Were in Toledo sop it's cold and snowy. I thought it need some fuel cleaner, I picked up some and some antifreeze filled up the tank, added the cleaner. The coolant wasn't low. Suddenly my temperature gage started freaking out and going crazy up and down and up and down if I had it on (recycle air it would go down faster). But it wasn't smoking or no other lights were on just the low coolant, then the service engine light flasshing ... Then next morning we went to start it and the oil started speuing out from the filter area. Now it's possible I may have a cracked block. So my advice : DON'T DRIVE IT!! take it straight to the fix it shop other wise you may loose yours too. It sucks. Sorry
That white smoke is burning coolant. You have a blown head gasket or a cracked head. STOP driving this vehicle, or you will destroy the engine. Coolant has entered the combustion chamber and the lubrication system. The head must be removed, inspected for cracks or warping, and a new gasket installed. Flush the cooling system, inspect the water pump, and cooling fan, and replace the thermostat. Pour in a fresh supply of a 50/50 mix of coolant.
