Have a 87 chevy 1/2 ton with 350 v8. Installed a rebuilt 350 put a set of headers on it and elimated the air pump. It starts but will not idle the O2 sensor is not connected. Will the O2 sensor disconnected cause it to not idle. Also the guages do not work could be a ground are these two problems connected.
