I gutted my catalytic converter as a cheap alternative to a test pipe. I am having a fuel economy problem and believe it is because my O2 sensor is detecting "dirty air" yet my check engine light is not coming on.

Is there something to trick the O2 sensor in the catalytic converter? or what? Is there any other common issues that affect fuel economy that i can check?

 

hey guys is there any help out there?

 

I find it hard to believe that you gutted out an obd2 cat and didn't throw the infamous "ineficient catalyst" code.

 

no man, my check engine light hasn't been on in over a year, knock on wood, and i did this around 6 months ago.

 

so is there a fix for this other than a new cat? or is their any other common reasons for a lack of fuel efficiency?

 

whats your average mpg? how many miles on it?

 

i have been getting right around 20/21 mpg and i have 81k miles on it
