Just bought a 95 Turbo Cobra, first forced induction car so I'm really new to this stuff. It has an innovative air fuel ratio gauge that reads 21.7 cruising then will drop to 7.4 when I push the clutch in. I know thats wayy too lean but I have dyno sheets from when it was tuned less than a year ago and no major mods since. The builder is a buddy of mine and says to get a new wideband sensor from innovative, just wanted some more knowledge on the situation...car runs great and I know bad o2 sensors typically make cars run like crap?
