Catalytic converter
I have been getting some bad gas milage and was wondering if replacing the catalytic converter would help. Just had tune up about 2 months ago and had the fuel filter changed in the process. Any ideas? It's a 91 v6 3.0 with 186,000. I also have engine light on. I'm thinking it could be the o2 sensor could that effect the milage?

O2 sensor can affect mileage.

You can go you schucks or pretty much any local auto parts store and they should let you use one for free in their parking lot. CEL = Check engine light.
