I have the same truck with about the same milage and am having the exact same problem. When I explained the problem to the mechanic, he informed me that I need to change spark plugs, wires, cap and rotor. I changed it all right after attempting the computer reset that you mentioned above. Nothing seems to be working. In fact it seems that it's gotten worse. Now that tac is going crazy earlier and more frequently.
