question about air/fuel guage

[Silverbird2002]

I just got my new guages installed today but I was driving home and noticed that my air/fuel guage jumps all over the place. it really doesn't stay in one place the only time it really changes is when I really get on it. The guy told me that it's because I have a narrow band sensor. Does this sound right or what???? Oh yea I have the auto meater phantom series 2 air/fuel part number is 7575

Are you running off a narrowband sensor or a wideband?

sounds like your running off the stock narrowband, so whatever it says is pretty much incorrect.

[slow6]

the only thing the stock narrowband sensors are good for is finding Stoichiometric AFR which is 14.7:1 AFR
but dont trust a narrowband

the thing is, the car is designed to go from rich to lean and back and forth real quick. the car wont stay at a steady 14.7a/f. so when you see it bounce back and fourth, its acting properly.

dont mean to jack this thread but i wanted to get some gauges, and AFR was one i was thinking of getting, are they hard to install?

anyone have instructions on installing say, AFR, voltometer, and engine temp?

thanks

strt racer I have AfR, trens temp, and fuel psi. I would go with Auto Meter gauges, and the install it depends if you want to use the stack sensor or if you want to put in a new one I would recommend putting a new sensor to get a more accurate readout , the install isn’t that hard do
