Having problems with your 1988 Ford F 250 ?
I have a 1988 Ford F250. As of late it has started to stutter and chug. The rpm odometer states that it is idling fine...no jumps in rpms. I'm not sure where to start at.
Check(replace) your external fuel filter located on driver side frame rail. pound(not with anything sharp or hard!) on fuel tank(s), as they have a screen in them to filter fuel, and also can clog. Check air filter-if dirty, blow out, or replace(recommend replace). Is engine check light on? It could be an exhaust oxygen sensor that's bad, or the catalytic converter is clogging. When was last tune up? If this problem had a gradual onset, it may need a tune up. There are other, more complex problems, - try these things first.
