It's called the EEC (Electronic Engine Control Module) or the PCM (Powertrain Control Module) It is located under the instrument panel on the floor tunnel ahead of the floor console. It has a ton of wires going into it.
The ignition module is mounted to the side of the distributor. It a rectangular piece.
If by control module you are referring to an ignition module then you need to remove it from the distributor and take it in to a shop for testing ,it requires special equipment for testing.A new module runs from $50-$100 depending on model
Powertrain Control Module
Please check your spark plugs,wires,distributor and rotor or the ignition coil module. My '93 LX has an ignition coil module.
I am pretty sure that it is on the right side of the battery behind the fuse box in both the 1.8 and 1.9L models
Not sure on a zx2. On an Escort LX it is behind the fuse box in the engine compartment.
Timing belt ?
The ignition switch is where you insert your key to start car
I am sorry, I can't for the life of me figure out what you are talking about. Unless you mean an electronic MODULE. If that is what you mean, then there are several electronic modules on the vehicle. The main engine computer(PCM), the electronic ignition module, the cruise control, air bag module, even the radio is an electronic module.
Recently had same experience with my dodge and escort. in the escort it was the distributor and the dodge was the brainAnswerCheck your ignition module in your distributor that is a good place to start.
I would check the ignition module located immediately to the right of your valve cover. A friend of mine has a Chevy Corsica that had the ignition control module or coil go bad and his car ran terrible. Ford stopped using distributors in Ford Escorts and their other 4 cylinder cars, because the TFI module on the distributor were notorious for going bad.
There is no governor on a 91 Escort. There may or may not be a maximum rpm limit in the ignition module or computer, and there may be a maximum speed (mph) setting programmed into the ECM.
