How many sensers do you have to put on and do you have to drill on the mid pipe for a O2 sinser

 

manifold air pressure is picked up from the throttle body, TPS is built into the throttle body, coolant temp sensor is mounted in line on a coolant hose and an O2 sensor is installed in the exhaust pipe. pretty straight forward. There is an air temp sensor that needs to be in the system as well, that's all I can think of right now.

 

who put the O2 sin in the mid pipe for you

 

anyone that can weld can put it in. Maybe 20$ bucks at a local muffler shop or something.

 

Or pay for shipping to KMS and Kelly will weld the bung on for you
