om651 jerk under load
Hi, few weeks ago I was driving on motorway and my car (r172 2014 - 63000miles) starts shaking under load. I made it back in workshop, checked injectors and found nr. 3 stuck. After few hours fighting with that I eventually got it removed, installed refurbished one and coded it in. Since that Im having night mare. Intermittent black smoke and engine light on, lack of power, shacking on idle and jerking under load.. Sometimes is better sometimes getting worse. Pulled code is P047128 even after replacing the back pressure sensor with new Febi part. Smoothness operation of cylinders is 10, 9, - 30 and 7 no matter how I swapped injectors around. Compression test runs on Thinktool PRO scanner shows differences just up to 5. I replaced all injector connectors, i done all applicable learning / teaching processes and nothing changed. Could someone light the bulb on the end of tunnel for me please?
Thank you
