idle it sohuld be bouncing. as for the others it depends on how u are reading..whether it be too rich or too lean.

You bought a blinky light show.

I have a Querstion....

What happens if its Not Bouncing @ idle but it starts to bounce and read the A/F when you have your foot on the gas , or driving. Could that be a bad ground or power??


Dave

If you are cruising it will go back and forth as the ECU adjusts the A/F. for best gas mileage.

But at idle it should be Bouncing back and forth , if it dosent show ANYTHING at idle , could it be ba bad ground or a bad power wire? i mean it works fine when im driving.


Dave

It could be. I would double-ckeck the wiring but those A/F gauges aren't very good or accurate to begin with. As cuc stated you just bought a blinkity light show with no real tuning value.

yeah i know they suck but it works pretty good on MY Grand Prix Gtp. Im gonna check the wires , i hopethats all thats wrong
