My main scan tool does not. I did borrow a friend's unit that will connect to my PC and uses ScanXL Pro. I will give that a shot this afternoon. I also realized that I could actually replace the plug wires, and that I have not. I may just pick up a new set of plugs and wires today just to make sure that is not the issue. I'll let you all know what I find out. Thanks!

if you had a coil going bad it would be running a lot worse, the coils don't just get faults they go out. Each time i have replaced one it threw a code and if you have a good scanner with full diags then it will tell you which piston is acting up along info to differentiate what part is acting up.

A quick test you could do is put it in drive and step on the brake. Give it enough gas just before the tires break free. If your truck cuts outs at that point you will feel it almost stall and if you can keep a steady RPM a that point then you will feel it in your seat. That is usually a coil over, wire, plug, or injector. Not saying this is a set test to figure it out but gets you closer to ruling things out to find your problem.

Thanks for all of tips! I did pick up a new set of wires, after realizing they had never been replaced. DOH! And I also bought a complete set of NGK G-Power spark plugs to replace the V-Power plugs that were in the engine. After changing everything out, my truck is back to it's old self. I believe that a couple of the wires were going bad, as two of the plugs I pulled out looked like crap. So, after utilizing my Advance Auto discounts, I managed to get everything for just over $50 after tax. Thanks again for the help and ideas!

I just got my truck out of the shop. I replaced all of the sparks and cables but my issue was all of my o2 sensors went. after replacing that and my vent solenoids my truck is running perfect. I am glad i had a warranty.
