I have a '94 explorer that all I've ever done maintenance wise are oil
changes, lube and air filters. It now has 61,000 miles (I don't drive it
much). Do I need to do some other maintenance such as fuel filter, spark
plugs and wires, etc? It runs great and just passed California enhanced
smog check easily. Thanks.
You are certainly running on borrowed time with almost 12 year old
belts and hoses. I'd change those.
If you just passed the emissions tests, I wouldn't worry about plugs
and wires. The fuel filter will let you know when it starts going bad,
and it's not likely to strand you the way a bad belt or hose would.
Besides changing the fuel filter is a pain.
Check your owner's manual for more things Ford might suggest.
