1996 ford escort 1.9 L mileage 91,000. Engine runs fine when cold, as soon as it get to normal operating temp, loses power and sluggish when starting from a stopped position. Already replaced EGR solenoid, EGR working fine , replaced front oxygen sensor, replaced catalytic converter cause it was glowing red. None of the thing solved anything and converter still glows red. No codes showing up either. Also getting extremely bad gas milage used to get about 300 miles per tank now getting about 150.

Suggested Repair

Check the fuel pressure regulator and fuel injectors for a rich condition that dumps raw fuel into the exhaust, which can overheat the catalytic converter and cause hot power loss and poor mileage.

Conversation Summary

A 1996 Ford Escort 1.9L runs fine when cold but loses power and feels sluggish from a stop once warm. The catalytic converter glows red, fuel economy has dropped sharply, and no codes are present. The EGR solenoid, front oxygen sensor, and catalytic converter were already replaced, and the plugs and wires look good. Experts suggested unburned fuel in the exhaust, a dumping injector, and the fuel pressure regulator.
