Air/Fuel ratio gauge

75

Asked by Nov 09, 2013 at 12:36 PM about the 1997 Volkswagen Jetta GL

Question type: Maintenance & Repair

i have installed a air to fuel ratio gauge on my car and every time i go to turn my lights on
or something along those lines my gauge bumps up a few notches i have the red power
wire connected to the number 15 fuse in my fuse box. is there a way i can get it so when
ever i turn on a light it does not bump up a few notches?

maybe try an inline fuse from battery direct, maybe the ratio is changing as the surge is made up by the alt. and split second pcm. adjustment to compensate for alternator load. or this gizmo has its quirks as a lot of aftermarket products and defies their claims. its about selling you something you know. if you added all the fuel saving devices claimed. your car would be perpetual motion in action
