Hello everyone.

I recently installed an Autometer Air/Fuel Ratio gauge on my 04 DTR. I used what I think is the lead wire on the driver's side upper oxygen sensor.

When I start, let it idle, or even drive/race, the gauge bounces back and forth between lean and rich. I doesn't settle down.

Has anyone else had this type of problem/bad luck? Anyone know how to fix this? Or was I really dumb and connected it up wrong?

Thanks for all your help!!
