Greetings! I hope I don't get banned for asking Q's about a 116 here. I've tog
I have a 1980 300SD. It has lacked power for the past 5 months. And the amount and duration of the lack changes from one trip to the next. There have been a couple of occasions when it drove just as it ought to. Nothing happens at the RPM when normally the turbo creates the kick we're used to (2100rpm).
On some trips, the car will BARELY move. Gradually it builds speed--very, very slowly. But it will no go faster than 60 km, and a that speed the rpm's are at about 3600--way too high.
I have investigated, cleaned and snooped the following places:
-clean the ALDA and line
-checked the leak down on the ALDA itself.
-changed primary and secondary filters
-changed air filter.
-turbo is fine.
-yesterday, I removed the fuel tank and looked at the screen in the bottom. That was less work--although dirty and stinky--than I expected. I will try to attach a pic.
A neighbour of mine told me of a story about similar fuel starvation type symptoms he had with an old snowmobile. The fuel broke down the fuel line in one section, and the hose collapsed, like an artery, when the pump created a vacuum in it. Thus, at high demands by the carb, in that case, the machine would starve and stall.
My car died on the highway after about 15 minutes of 60mph driving. I'm beginning to think the fuel line collapse story might be relevant. If I bleed the fuel system at the main filter, the car will start. After about 20 seconds it slowly starves and turns off.
Does anybody have a suggestion? Could it be a vent problem? Maybe the tank vent is blocked? Should I replace sections of rubber hose?
I'm attaching pics of my fuel tank screen (123 part number even though my car is a 116). The tank appears to have been free of fungus/algae/small rodents. Or is my line of thinking just wishful thinking--is it a problem with the IP, namely?
