How many miles? Any CEL codes?
Do the el cheapo catalytic converter test for the Zetec 2.0 DOHC 4 cylinder
1) Disconnect negative terminal battery (note you will lose all CEL codes stored in the PCM memory)
2) Disconnect Upper O2 sensor connector
3) Remove Upper O2 sensor (use 7/8 inch or 22 mm crescent wrench or O2 sensor removal tool).
4) Reconect battery and drive.
What you are doing is give the exhaust an outlet. If car performs better, you probably have a plugged catalytic converter.
