A piss in the wind diagnosis:
Exhaust leak, and the O2 sensor is getting a lean signal.
A 95 being OBD2, the secondary O2 sensors aren't getting a variable reading
from the cat if there is an exhaust leak too.
I hope this helps.
Some have the OBD2 engine management and some don't>
I'd figure ford for a shithouse contraption like that, not GM.
I guess they all suck now.
An exhaust would act the same on an UBD1 also.
