I am going to get new spark plugs and spark plug wires soon is there anything else anyone would reccomend changing at the same time? It's on a 98 4x4 with 123000 miles on it.
Thanks

 

Sounds like a good plan. I dont know what engine you have but if its the 5.4 make sure to spray some penitrating oil on the plugs ffirst and when you take them out turn a quater turn then back it off. Keep repeating that so you dont break a plug off in the head. When you put them in make sure that you use antisieze compound on them. If your gun hoe you could look for an upgrade to your coils if you had the 4.6. Hope i helped you.

 

Thanks. Just curious I do have the 4.6 and was wondering what replacing the coils would do and how much more that would cost?

 

Go back with Motorcraft parts.And,use dielectric grease in the boots for the coils and plugs.
Change the pcv valve.Fuel filter.Clean the throttle body.
