W110 W111 W112 Sedan, BENZ AID - COMMON QUESTIONS AND ANSWERS

82 300D has slight miss. This engine has 157,000 miles on it and runs good at highway speed. I can losen the fitting on each injector and make it run like a gas engine when you pull a plug wire. Has only slight miss when all injectors are tight. There is definitly a lose in power at low speed taking off from a light etc. The injectors have been pop tested and all are good. Compression test shows around 325 to 350 psi on all cylinders. I have adjusted the valves twice to make sure one was not to tight.

I have a 1988 190d 2.5 liter NA. I started the car like normal except that the brake pedal was very stiff as though the power brakes had stopped working. Also when i went to turn off the car it kept running so i hit the manual stop on the fuel pump. So the problems are simultaneous. I heard that it is a possible bad vacuum but im not sure please help. thank you.

Hi all. New member as of today, and today I also picked up my 2nd Benz. I have some experience with my 1971 280S, but today, I bought my first diesel. The cars rather amazing overall, for a black on black leather car with original paint. One owner. 200K miles. A few little problems that I already see answers and/or parts for. Here's my concern. The car is amazingly slow from a stop to 10 or 20 MPH. Then it's decent, much like a gas car. I see an unusual "part", seemingly disconnected in the engine compartment. It's like a little frame with heavy coils inside of it. What is that part??? It seems to perform much better once it's warmed. I know NOTHING of it's history aside from a clean VIN check, one owner, 400 miles in the last 2 years and it was probably garaged.

Hey All... I am new Mercedes owner...I just purchased a 1980 300D and am currently running B99. I have a few new filters and my biodiesel gas station (biofuel oasis in berkeley) has monthly seminars on changing filters and all that.
