Hooked up the old (maybe the first) sunpro scanner and read codes 998, & 228.
Manual says 998 is malfunction allowing truck to be operated in limp home mode.
228 is primary coil failure-replaced the coils, four screws each-that was real hard, lol.
Master pro coils purchased at Checker Auto for 40.00 each with a one year warranty.
First trip was actually to Auto Zone in reference to my spark plug wires possibly being bad from them, and the clerk says return them. I said ok, thanks for the brand new plug wires at $0.00.
Went ahead and changed all the plugs while I was there, and since they were sitting in my toolbag for months.
Thanks everybody for the assistance.
P.S.-As far as the limp home mode is concerned I drove for a good week like this and had no problems at all.
