yes agreed,ive only ran the car twice since this has been going on and last time it was lean at idle and pig rich when it cut out seeing 10:0.1 afr.The way the turbo responds and sounds feels like a boost leak but smoke tested the entire system with throttle open and it holds boost.
However I did reuse the exhaust manifold gasket and wondering if I have a severe leak at the manifold which would explain the lean idle/slow resonse and possably the o2 sensor is making it jerk under boost?So today im smoke testing that exhaust side as well.
Thanks for the input and I will try and record the next time.
