Hey, I had a problem like this and solved it. Take a test light and check at the ecm for power (with the key on) at the orange and black wire. My car had a broken connector in the engine compartment that feeds power to the ecm. Take some electrical tape and wire covers off. It is where two large orange wires meet three small orange wires. After repairing that, my car started right up. Good luck, Ken- Martin Auto Body

Easy answer? bad spark plug. Check it. Next check? the wire. Substitude a good wire and start the engine. If it runs good, that's what it is. Next check? Coil pack. Or the gas injector. Next?

How do you check fuel injectors on 1994 ford escort?
With the engine running place a mechanic's stethoscope or screwdriver against each injector one at a time and listen for a clicking sound indicating it is working. IF an injector isn't operating or sounds different from the other 3 turn off the engine and take the electrical connection to the injector. Check the resistance with a DVOM across the terminals of the injector. It should be between 11 to 18 ohms. If it's not within this range replace the injector.

It may be map sensor but engine knocking cause of another reason.
