Is there any other possible fixes other than a rebuild?
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 4 months ago

yes, you may have a bad injector, have you checked compression on that cylinder yet?

Ford diagnostic showed codes PO284, PO308, and P200E Cylinder 8 misfire. Doesn't show that they did compression test
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 4 months ago

it may be just a bad injector, first they need to run a compression test, if that cylinder is below 400 psi, then , yes, the engine will need to be rebuilt, if it is above 400 psi, then its not an internal engine problem, most likely a bad injecor, how many miles do you have on this?

did the ford shop say it needs rebuilt?

Their diagnoses shows those codes, and says cylinder 8 misfire needs tear down and inspection
Ford Mechanic: Tim Mohr, ASE MASTER TECH replied 4 months ago

they need to first run compression check on that cylinder, before tearing it down, if they wont, then I would find a different shop, the compression test will tell if its an internal failure of the engine, or that its a bad injector,Tim

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
