I have an AEM fuel gauge. Simple question: why does it constantly bump up and down when I am cruising. Pretty much in a rhythm it will go from ~13.8 to ~15.3....bounce up, bounce down, bounce up, bounce down about once a second or faster. Never sits at stoichiometric for even a blink.
Now, when I go WOT it quickly drops to 11-11.2 and stays there. Just wondering if this is normal behavior. Thanks.
