My 1997 C200 petrol auto has done 144k miles. I changed the plugs some time ago. Recently, the engine hesitates on starting in the morning. It will stop if I engage the auto reverse or forward. I have to run the engine awhile before i engage the auto. I now always get this when the engine has not been used for a while during the day.
I have changed the two ignition coils but to no avail.

Does anyone have any guidance, please?

Bill
