If you decide to change your spark plugs then you must go and buy the plugs and wires,
Once you buy the plugs and wires you will find you need to remove the intake manifold and throttle body assembly.
As you remover the intake manifold you will need to remove the vacuum hoses.
Once you remover the vacuum hoses you will find some are dry rotted or have been chewed by rodents.
So back to the parts store for new hoses and vacuum fittings…
Once you arrive back you can now install the spark plugs, wires, hoses, and fittings.
Now that everything has been installed and replaced you an bolt the parts back together.
As you start you truck back up you notice you are idling too fast and need to check the engine code.
When you hook up your code reader you will find that you damaged your throttle position sensor causing the high idle speed.
Now you borrow your wife’s car once more to get a news sensor from the parts store.
When you get back from the part store you install the new sensor and crank up the truck to see it run smoothly once again.
Now that the truck is running well you can go inside and clean up since you now need to go to the parts store again so you can now change the oil in your wife’s car.
