whaoh....so im talking to darin, and make mention of my s#itty gas mileage, no performance (this, while im putting in a new crank gear to advance timing) engine, and he asks about my 02 sensor. i tell him i have a new one, a bosch, and he proceeds to tell me that that is my problem. darin, you suck <img src="/forums/images/graemlins/smile.gif" alt="" />. anyways, my idea is to plug up the bungelo at the pipes (its right where all the pipes merge), then throw a new bungelo past the collector pipes, where i can stick the sensors read area actually INTO the exhaust flow. anyone done anything like this, thought of doing this? thanks for any input.
