i got it hooked up to the tan wire with the white tracer like silver posted but now it just bounces from rich to lean is that normal
If it is bouncing from rich to lean, that is normal. Here's how it works when you have a narrow band o2 sensor. When you are in open loop mode (cruising, idle), the a/f meter will dither back and forth between rich and lean. The rate of the dither is important, and will indicate how good a job the PCM is doing keeping the A/F ratio stable under light throttle conditions. Should dither about once every second or so. Then, once you go into closed loop mode (like full throttle), it should peg on a single a/f number - probably on the rich side. This change from dither to exact number is because the computer is no longer trying to regulate your overall a/f ratio, it is giving you a reading for the exact mixture as you get on the gas and go into closed loop.
So if this is the behaivior you are seeing, then it is operating correctly. If you want an A/F meter that will give you a near exact reading under all conditions, then you need to install a wide band o2 sensor and get an a/f meter that works with that type of sensor.
