Hi all, I have a hybrid Gen3-4 car that Im having monster troubles getting to run properly. I am by no means a tuner and I am pretty stupid actually, as I bought this car is a great example. So my knowledge of Hp and tuning is rudimentary, so be gentle.
Stumbles at around 2-3k rpms and looks lean? I have a AEM wideband installed, but it keeps failing. Got yet another on order.
