I got my anderson PMS from Racer Walsh yesterday and Eddie helped me do an initial tune. What a difference, the partial throttle timing feature has unleashed amazing pickup. The car is riding better than ever.
But one thing that is definitely messed up is my o2's. I am showing no output to the computer. I know the bosch 02's are only a month old. I checked the voltage at the connector on the right fender and I got .5 volts +/- on the yellow striped wire. I cleaned the connector and reseated it and got a reading temporarily. However, the reading went slowly down to zero on the PMS within 30 seconds. What could be causing the voltage reading to slowly fade?

thanks, and thanks for the anderson pms recommendations...this thing is something else.
