If the bulb isn't in the socket for the check-engine light then you'll probably not notice a difference except: if it has an automatic transmission, I believe it will not ever engage the torque-converter clutch while it thinks the check-engine light is on.
it has one O2 sensor before the cat. Neither car has a true dual exhaust. I'm just changing motors and the rear end with a posi from the 97 and the posi is a disc brake rear end.
