ok so i just put some gauges in my 02 neon, i put an air/fuel gauge in and the needle goes crazy when car is started, how do i fix that

 

its normal theres nothing to fix it

 

a suggestion, I have a wide band autometer c2 in my 05. I had to get the entire kit with a wideband o2 sensor, then I had to drill a hole in my header and weld a bung on it to fit it. Works really well. A lot more accurate than regular cheap ones. But a bit more pricier and a lot more work. Factory o2 sensors will not cooperate with aftermarket a/f gauges. Been there.

 

ya, it sounds as if you have whats called a "ricer light show"... narrow bands are useless.

 

yeah. those a/f guages are crap. the lights going crazy when you first start the car up because the computer is using preset specs because the sensors cant get an accurate reading until the car is warmed up. doesnt matter anyways because the a/f sensor you have is non adjustable. get the aem wideband o2 sensor and guage kit
