I have an e 300 avantgarde td estate,98 model.It does not appear to be right somehow,after starting and of course in drive,I go up the first hill from my house and it starts to sort of jerk ! also it sometimes drops out of gear and goes into a nuetral state.I have to stop,turn off ignition and restart,and off we go again as if nothing had happened.This is starting to worry me,any ideas ? Thanks. p.s this is my first posting as a new member.
