A lot of people "in the know" will say this is not a way to judge your a/f by. It's a "narrow band" sensor and is only accurate when close to stoich. (14.64:1 a/f ratio)
However I've had my wide band hooked up for about 2 months solid. I watch it and I watch one of the stock 02s on my scanguage. And I'll tell you this. It's repeatable and accurate down to about the 12.0 - 12.5 area. Richer than that and there is not much difference... which is really too rich anyway.
I'm confident enough in having compaired them side by side that I've taken the wideband out of my truck and just use the scanguage. Next summer I'll most likely spray like this too.

okay so i hooked th wire to the grey/w blue wire and iam haveing the problem with the check engine light comes on every once and a while and goes off. i have the codes ran and it says that the mas air flow sensor has failed it didint start doing that until i hooked up the gauge ( i have hooked thses up before and never had this much problem) the truck still runs fine with the light on but how do i fix the problem with the gauge messing with it.
