99 expedition spark plugs

[Petrafire]

hey just bought a 99 expedition its misfiring quite a bit around 55 km/h im thinking spark plugs and have no idea how to change them is there a thread somewhere with pics?

having changed mine and the ones in my V10 excursion I would say if you really dont have a clue take it somewhere. If it costs $100 its honestly worth it to avoid the aggravation of doing it yourself. Not a fun task

I put a ZF 6 speed in mine myself, but paid the shop to do the plugs.

x2 on dropping at the shop.

It could also just be a coil going bad. Get it scanned for codes and tell us the results.
