i just installed hotshot headers on my 95 240, but now i'm running into trouble. i had to replace one of my o2 sensors (the one on the header) now my check engine light is on, the cat was hollowed out when i bought it, and it is putting out alot of exhaust fumes. do i need to change both sensors at the same time? do i need to replace the cat? or reset the computer? help please!
