AIR fuel gauge
air/fuel gauge.. Yes I know its not going to be perfect, and its accuracy is not going to be great, but I will have an idea...
BUT can anyone give suggestions for this...
Not sure if 02 z28 has more then 1 oxygen sensor, and if it does, should I do the sensor in front or back????
I dont have car at work today so I cant run out there and take a look.
but any suggestions help..
Thanks all..
