running bad
 

hey guys I am new here, I am having problem with my 1984 300 d turbo, when I start the car it runs smoote but when I shift to drive the first two gears is fine and them the car seems like is something hold and you can give gas and nothing heppens, it doesn`t go over 30 miles.

Tune it up: new fuel filters, air filter, valve adjustment, oil change, etc.

I'm having the same problem, came to the forum for input. I have a clear plastic hose for the return fuel line. I'm getting air bubbles, so I know that I've got an air leak somewhere. Tightened up every hose clamp I could get to, found a few loose. Runs better, but still won't rev past approx. 3/4 throttle. Bubbles are now less, but still seeing them. Diesels and air in the fuel don't mix.
