Get the codes read out .. maybe at autozone , come back with CODES!!!, not the description

Sleepy,
Welcome to the group! Trust me, Backyard is a very nice (not to mention incredibly knowledgeable) guy. You may not know that, but posting on usenet in all capitals is considered impolite and, on a more practical level, makes reading very difficult. So please help the experts (that description will not include me...) who so generously volunteer their time and wisdom to this group to help you.
Good luck getting your truck back in order!
Any chance you have a coolant leak?
Is the check engine light flashing, or just on solid? If the light is flashing, you most likely have a solid misfire on at least one cylinder. I'd suggest taking it to an auto parts store like AutoZone that reads the codes for free. The code will tell you which cylinder(s) is misfiring and you can go from there.
If you have a 5.4L, I'd guess you have a bad coil pack boot. But since you say you have replaced the spark plug wires, you must have a 4.6L - in which case I would suspect a bad plug wire, or a bad coil. Either way, having the codes read should go along ways towards identifying the problem.
Regards,
Ed White
Why are you guys asking for clairvoyance, when there is real information available? Read the codes, for goodness sake. That's what they are for. At the very least they will point you to the cylinder with the miss.
