Installed a new AEM wideband and sensor on the weekend. The issue is after letting go of the gas say on the hihgway or slower roads the gauge gets the horizontal line reading (no input?) until I hit the accelerator again
It's as if it hits maximum lean or no gases to measure, but that's not possible because the car is running and idle is fine as well as neutral decelartion.
It starts up fine and settles down on idle and all through boost holds it value but +/-.2 v.

Sensor was installed on the downpipe at more than the minimum 10Deg angle. I thought I was getting a sketch input voltage from the switched source but getting a better source didn't help.
Screw on the back of gauge is in the P0 position.

any input and ideas will be welcomed.
