Well today has been kinda crappy. I've been looking into turbo'ing the tib for awhile now. Just for kicks, I put in an air/fuel gauge last night, and its reading completely sporadic. Up and down. At first I thought there was something wrong with the gauge, but then I started thinking. While it reads slightly sporadic normally, it'll go all over the place whenever I use anything electrical on the dash. I've always had some minor annoyances with the electrical system inside the car. Whenever I use anything, including the rear defrogger, the heater, or using the brakes, thereby illuminating the tails, the entire dash dims. So I figured that maybe, since the gauge is wired up to the fusebox, that I need to either ground the inside fusebox, or re-ground the entire car's electrical system...any ideas? Wheres a good place to ground?
Oh and I've had the alternator tested today actually, and it ran brand new, so I'm sure its not that. Any help would be greatly appreciated... |
Did you put in a wideband O2 sensor and A/F gauge or an A/F gauge that you wired to your stock O2 sensor? If you are not using a wideband up and down sporadic lights is normal operations for your A/F gauge.

ah I was wondering about that. For now its just wired into the narrow band until I got the money to sink into a wideband. But I should've thought of that. But I still don't exactly know what to do about the dimming of the gauges. Its like the current isn't stable. Should it be re-grounded? Thanks for your advice on the wideband, forgot about that... laugh.gif
Is it possible to wire this A/F gauge into the wideband later? |
I don't think you can use that gauge with a wideband. Chances are you need to fix a ground somewhere.
|
Java's right. The stock o2 sensor only reads lean or rich after it heats up.
... but it sounds like the gauge was designed for a wide band o2 sensor. |
^^^Well I won't know for awhile. From what I've seen, Wideband sensors cost around $300, although I could certainly be lying. Where'd you guys get urs from?
