E350 m272 slight shake or shuddering while in sport
Recently got a 2010 e350, car had a missfire which turned out to be 3 valves. Valves changed resurfaced check engine left. Later came back and started noticing slight shaking when im sport coming to a stop or slowly letting off the gas pedal. Engine light came back, went and changed injector and coil the shake would stop for a few hours and then come back usually is noticeable in reverse and sport mode. Changed ecu drove fine no shaking whatsoever, turned car off and on and the shaking appears agains. Opened valves again to get it checked they said they looked good but still the issue keeps happening and no check engine light!!!!! Might it still be the valves or something else? Anyone had any issues like this

This amounts to reduced engine performance.
You may want to:
- Scan your chassis for faults
- Read your LTFT fuel trims
- Read the fuel pressure
- Double-check the broken intake flap actuators
