    So I'm having issues with tuning my car. Appears that I have a stuck injector but I dont from bench testing. car smokes llikes crazy and wreaks of fuel but AFR is hitting 14:3. We have cut fuel to almost have with no fix. plugs looks fine I'm so lost idk what to look at. Any ideas?

    Trust your nose more than the AFR gauge. It will read lean when there is unburned mix (which happens when it is super rich), and is an average of all cylinders.

    What ECU? Can you post more information on conditions(idle, wot, etc) and setup? A log would be helpful
