According to my COBB Accessport my 4th pistons has been misfiring as well as rich fuel mixture. The car runs smooth, screams like a crazy banshee when WOOT and idles fine. But I have been noticing my air/fuel gauge has been going crazy at times but usually stabilizes quickly, its that normal? I am lost as to what is causing this. I do have lighter flywheel, coils, and bigger fuel injectors. Thanks
