Gonna have to be more specific than that. Not enough to go on.

Just slow, not stupid.

gas furnace limit switch

A coleman could appear to short cycle from a poor thermostat location, a faulty anticipator setting in the thermostat, a dirty air filter, too many hot registers dampened down, a partially obstructed return air grill, a crack in the heatexchanger near your bi-metal fan control, improperly adjusted fan/limit controls and on & on.
Is it your thermostat that is going on & off?
Does your coleman have a fan control that will show you the on, off & limit temps?. Watching what they show of your operating temp is a quick display of the possible problem. The real easy possible fix would be if your furnace filter is just dirt plugged.
