1985 300D water leak

Despite replacing the windshield and rear window seals, the door window seals and the sunroof seals, water still puddles on the floor of the front passenger compartment. I have looked at the drains under the hood hinges. They seem to be clogged but I can't get a wire very far into them and it seems impossible to blow them out with compressed air. Where do they exit? Can one clean them from the underside? The repair manual on CD I got from Mercedes is no help. A lot of the information (visuals)on that CD is very bad quality. Where else should I look for possible water entrance points?

1982 300D rough, low idle during warmup only

My problem has been coming on slowly, it seems whenever starting the car hot or cold i have to depress the accelerator pedal once before turning the key and it will start no problem, use to not have to do that. now that it is getting colder outside after doing this procedure on the first start of the day the engine seems to have a low rough idle and sometimes have to hold the accelerator with slight pressure to keep the car from stalling, also some of the time the idle will slowly surge a few times, once the coolant temp gauge starts to rise the problem will go away.
