You own a 1991 escort gt and need to know how to get the ecu codes from it the problem is that the car is running rich and after a minute if you drop the pedal the car bumbles a lot then accelerates?

To retrieve the ECU codes from your 1991 Escort GT, you can use a jumper wire to connect terminals in the diagnostic connector (usually located under the dashboard). Specifically, connect the terminals labeled "TEN" and "GND," then turn the ignition key to the "On" position without starting the engine. The check engine light will flash, providing you with the trouble codes to help diagnose why your car is running rich and experiencing acceleration issues. Make sure to refer to a service manual for the specific codes and their meanings.
