At idle my wideband is pegged at 22.4, when throttle is applied it reads "normal" A/F ratios, but as soon as I let off it pegs back to 22.4 also if I just ease into the throttle it stays at 22.4, I know it's not lean, it's leaving black marks out the tailpipes. Sensor has maybe 50miles on it. Ideas? On3 kit, sensor is in supplied downpipe bung.
which innovate kit is it? i had the older one on my turbo car before, the one with the free air calibration bs, and it was a constant headache. changed to an aem and no more bs. my pro-m efi uses the newer innovate units and so far so good.
also, no matter who's product you're using you should be running as heat sink as they all use oem 02s which simply can't handle the heat soak
