2002 Sport Trac --- How often should spark plugs be changed

[karenwmeyer]

Not having any specific problems, but I don't recall ever having them done and I've got 125K miles on it now. I'm thinking of driving across country again in March and don't like "repairs on the road".... so I try to keep ahead of the game.

I would look in the owners manual, but someone did a "grab and go" a few years and stole it from the glove box... you know, that nice leather case it came in made it look like something special I guess! Thanks! I'm getting kinda leary about driving the old gal so far (Nevada to Boston and back), but I'm guessing I can get another 6K miles onto. I've done 4 cross country trips with it already, but the older we both get, the more risky it seems! Just trying to head off any road repairs....

I believe the manual stated 100,000 miles. I would do a plug, coil pack, and wire replacement before the trip. I take it you do a lot of highway miles to not have misfire issues yet on that miliage.

Thanks. Most of the mileage is from living in remote areas... out here in Nevada, driving 3 hours round trip to do grocery shopping is not unusual. Now I live "in town"..... so I haven't put many miles on the past few years.

Glad the forum could help. Safe travels.

Every 100,000 miles change the spark plugs.
