Answers :

If you know the plugs are good, then start the truck up, if the engine is jerking a little while idling unplug the alternator and if the engine smooths out replace the alternator, it can have an internal short that can cause that.
All you need to do, is buy one new coil,
\015\012one time at auto parts store $60.00 once
\015\012
\015\012One bolt,you can install the COP Coil in
\015\012less then 30 min
\015\012
\015\012You disregard the PO303 Code and walk
\015\012the new coil until you find the bad one.
\015\012
\015\012You can do one or two cylinders a day,driving
\015\012at least 25 miles and getting it hot in between
\015\012
\015\012Codes don't always match up to the problem cyl
\015\012
\015\012When it isn't corrected put the old coil back where
\015\012it was, move the new one to the next cyl
