Ive read alot about removing my catalytic converters and replacing with bypass pipes as I have just got 4 different codes from
sec air
heat 1
heat 2
O2 sensor
If I remove cats will the engine light stay on and how hard to reprogram ?
I drive under 5000 a year but she is my daily driver
any thoughts appreciated..

Removing the cats won't repair the o2 sensors.

Yes.

Very difficult.

Chris,
Go to your local auto parts store and have them read and clear codes for you. If they won't do it, buy a reader (under $40 easy, some now under $20). Clear codes and see when they come back.

You can remove rear cats and replace with bypass.

Don't remove front cats. Just replace forward O2 sensor(s) if needed.
