I've put new spark plug wires and spark plugs, cap, and rotor on it but that was after 105,000 miles.
I had to put a new back gas tank, the other one rusted out.
The transmission fluid and filter were changed.
Great truck, with very little work to be put in it.
Nothing has really went wrong besides some minor stuff that happens in every vechile.
Gas mileage is very good, about 23 on highway.
I have a 1991 ford f-150 and all I have replaced was the gas tank rear wires plugs transmission filter and regular maintanance.
