My 1995 Trooper S has started to hiccup. When setting at a light in
gear, the engine drops, only for a sec and not even moving the tach. I
heard this a couple of mothns ago and thought it was just bad gas
because it "hiccuped" while going about 45 mph. It only did it at speed
that one time. I ureplaced the fuel filter, air filter and the spark
plugs. I am just not sure what else it could be.

Any advice is appreciated, TIA!
