Cold start reduced power
I’ve been having a weird issue with my cls 550 (m278) I recently did a valve cover reseal along with front timing cover reseal along with a new thermostat and spark plugs and one ignition coil and turbo and oil coolant lines. I noticed that the first start up after a cold start the car has reduced the power even when it’s warmed up it’s still not moving as fast as it used to until I restart it then it’s back to normal.
