What would you like to 1995 ford probe kickdown solenoid?ask?

Although these cars are known for their automatic transmissions going bad, I would suspect the catalytic converter of failing. Sometimes on OBD1 cars such as yours, the ECU can't detect that the catalytic converter is failing, but instead throws a code for a failing o2 sensor. I would disconnect the exhaust before the converter and test drive it to see if it makes a significant difference. If it does, you know you have a blockage in the exhaust which is most likely the catalytic converter.
