i got an autometer narrowband air fuel gauge. it seems to jump aroun d more than i thought it would. the gauge is good. now for my question. could it jump around due to me having a heated 4 wire 02 sensor instead of a single wire 02 sensor. i know the signal is suppose to be the same. but!! would the newer 4 wire 02 sensor read faster than the older single wire 02 sensor causing the gauge to fluctuate so much.
