got 2 questions today...1st: I noticed that one of my injectors was leaking(2nd if looking from front of engine) and decided to replace the O ring since i was going to replace my valve cover gasket. I replace the O ring and noticed that a little rubber bushing type thing that sits below the fuel rail wasn't as tight on the "bad" injector as on the other ones, I go to the store and pick a new rubber bushing thing, then replace it. Well it didnt work since the gas is still leaking from the underside of the fuel rail only on that injector,,would i need to replace the whole ionjector??

2nd: I tried to hook up my A/F gauge, I used the radio + and - for the gauge but im having trouble with the o2 sensor one, at first it wouldnt work but know it does, only one thing though, it makes the cars idle and acceleration pretty crappy and only when the gauge is connected. The gauge is connected to the green wire coming off the o2 sensor before it connects to the thick black sensor wire...any help or tips appreciated. Thanks
