I have a Ford Probe and the catalytic? Converter was taken off now I have poor gas mileage, sputtering etc. I'm assuming its the oxygen sensor not being hooked up to anything is there a way to override that sensor?
First, it is a federal law that the converter be on the vehicle. Also, now that it is missing, the computer has no idea what is happening without info from the O2 sensors. As a result, it goes into a closed loop setting and runs the vehicle very rich. You need to get things back together on the vehicle.
