Exhaust question
 
I recently removed my cat 2 weeks ago and now my 1984 z28 has started the same symptoms as before. I've tracked the issue to my o2 sensors. My question is how can I make my car work correctly by either eliminating or fooling the o2 sensors?

What are the same symptoms as before, and how did you track the problem to the O2 sensors? Removing the cat isn't going to change how the O2 sensor adjusts the air/fuel mix, as the sensor is located before the cat. And your car doesn't have a monitored cat (post cat O2 sensor equipped), so your computer doesn't know the cat is gone.

That's what I thought also. I have an obd1 abd its spitting out codes for both o2 sensors. Could it be as simple as just replacing them both? The same symptoms such as no power. Bogs down as you give it more gas. Won't idle.
