My little truck died. I have replaced plugs, wires, head, intake coil pack, hoes, belts, air filter, and thermostat. I wasn’t getting fire on the # 3 cylinder, but had fire on all 4 on the exhaust side. Swapped coil packs and had the same problem. Put a new coil pack on the intake side and now have fire on all 8. Had the ignition mod tested and it passed 5 times in a row. I have gotten the truck hot while running rough and still had fire at all 8. It will crank and run good, once warmed up when I stop acts like it wants to die. Any suggestions?

Pull and clean your IAC valve, replace if needed.One trick that I use sometimes is to go to salvage yard and try a different piece, to see if any differences can be noted.
