Greetings!

I got the gauge wired and the sensor installed but have a problem. The gauge is showing 3 dashes and the outer ring lights peg when I plug in the sensor.

I can't find a THING online about the reason.......HELP! "please"
 


Try patting the gas a little at idle, just enough to get it to rev a tiny and drop off suddenly, You should be able to get it to swing into the readable AFR, if so, you are crazy lean.

Tried it...still have dashes. Should it have the dashes even when it's not plugged into the down pipe? I may have a wiring problem, but, I doubt it.
 


if it has no data from the sensor it will stay dead on 14.7 the entire time (IE unplugged)

Just dashes means lean as **** or rich as ****.

Does it give you 2-3 letter/number combinations when the gauge turns on?
 
The harness is plugged in to the sensor. Dashes is all I get. Mount the sensor in the downpipe, start car, dashes is all I get.

So, the gauge must be getting data. The car smells really lean, but, I have no idea how to check or change that.

Wouldn't the plugs be turning black in a really lean condition?
