bahahahahaha didn't think so. try the plugs and coils first man, i seriously think that's your problem especially if you have 230k on the original. you truly could have a bad coil, i have heard of that before happening, it's not that uncommon
Big'un your my little jigger but your to impatient. Replace all plugs. See what happens. I bet it fixes it. If not start checking the cops. Unplug one at a time with the engine idling. You be able to tell which one is bad.
the code wont change right away. the truck has to be ran and stop a coulpe times to read a new problem. unhook the battery and then put another coil on the one your having problems with then reconect the battery and see what happens
