My 85 Colt starts fine when cold. After warming up it begins idling rough and will stall. Hard starting when warm. To get it to start after it gets hot I press the accelorator all the way to the floor and crank away until it sputters and spits to a start. Almost like it's flooded.

Engine light could be from the spitting and sputtering, sounds to me like maybe bad spark plug wires, possible an ecm issue, what kinda code is it giving you when the engine light comes on?

Most likely you have a bad Idle motor which is a small motor mounted on the intake manifold. If the motor can run better with your foot on the gas but dies if removed then it is probably this. This motor is controlled by the OBDII computer which gets it's control signal from the temp sensor which is located either on the radiator or engine block (which could also be bad), if the electric fan (if equipped) turns on then this is not the problem part, but the idle motor is. Another possibility is that you have some bad /cracked vacuum hoses which should be checked for first, before replacing the idle motor.

One of the more common problems with the 2.5L & 2.2L engines that suffered the symptoms your describing, such as, starts & runs good, then at any given time would just quit, not start, but after sitting a while, or by the time the mechanic gets to it, it starts right up, or you sit on the side of the road for 20 min. or half hour then away it goes for a while longer, then quits again down the road. There is a pick-up plate under the distributor cap & rotor, with the wiring plug coming from it. 90% of the time, it's defective, and cuts out especially, but not limited to, more often when weather is hot.

you have a bad crankshaft sensor. replace the crank sensor.
dodges and gm's are known for this problem.

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them. Air filter, same thing. Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from. It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).
