'84 300CD Power loss

I've got a Turbo 300 CD Coupe that I've just purchased about 2 weeks ago. It's got about 270,000 miles on it and was running great until a couple of days ago. Now it seems to hesitate a bit (stutter) at speeds arounds 60 mph and if I'm going up any sort of hill it slows down pretty dramatically, like to 35 or 40. Also am noticing a bit more roughness in the idle. Anybody have any ideas of what it might be or how to diagnos this?

1984 300d Ignition switch Woes and advice

I just had a problem with my ignition switch and want to give some helpful advice to others so you won't have similar grief.My 300d has 223,000 miles on it and several times (not very often) the key would not turn in ignition,but I was always able to make it work by jiggling the steering wheel..until last time!No amount of jiggling ,light tapping,heavy tapping,or even the locksmith,could get it to move.
