the o2 sensor is a two wire and it is unplugged also. The guy said he put alot of money in this truck and said he changed the engine and it was beefed up but when I tore it down everything was stock and the block number said it was a 89 to 95 2 bolt chevy so i dont think he changed it. The engine light bulb is still in. It does not stay on tho. o2 sensor is a two wire but thats been unhooked the hole time. If I put a carb on this I would have to change nothing would I??? what about the sensor that plugs into the side of my throttle body??? I thinks its my TPS. My mechanic said I could hook a carb right up and it would ber fine. What do you think???? This TBI setup is just like a carb setup but with a computer, If i put a carb on i wouldnt need the computer right????
