Question about 1993 Ford F150 SuperCab

1 Answer

1993 Ford F150 smoke coming from spark plug

Originally I thought this might be a timing chain problem since the truck ran so rough but after taking the advice of a helpful person on here and installing new plug wires, distributor cap, and rotor I think I've isolated the problem to the area of the spark plug on the front driver's side of the engine. I'm guessing this goes deeper than a problem with the spark plug as there is grease or accumlated oil around the spark plug hole.
Thank you for your help.

If it's on the outside of the hole, it could be as simple as a gasket leaking from above or near. Oil on new spark plug electrode area, is something to be concerned about. Is the engine running o.k. now? What engine is it?

1993 Ford F150 FUEL PROBLEM


Sounds like one of the injectors is stuck open, or the fuel pressure regulator is faulty.
You can disable the fuel pump and see if it clears up right before it runs out of fuel pressure. You can also check the spark plugs for ones that are fuel soaked.

sounds like a vacuum leak still, check egr and also could be possible intake leak.
Spray bottle with water is best, and will run even more rough or stall when you found the leak.

My F-150 started running extremly rough and barely runs.


It seems unlikely it would be a timing chain issue. They are not really known for jumping and if it had jumped there would be other issues, not the least of which would be pistons crashing into valves if its an interference engine.

When was the last time a tune up was done? Perhaps new plugs, plug wires, distributor cap and rotor are in order based on the information you gave.

There could possibly be other issues, but based on what information you gave that is where I would start.

Miss firing


could be a wire crossed, or it's out of time. since you used motorcraft plugs, did you set them properly to the correct gap? replacing plugs without gapping them can cause the sluggishness, out of time can cause the mis-fires and rough running.
