Good Morning Folks.
I am returning to this website and group after a long two year covid induced lay off. I am not sure if Volker is still around and therefore addressing myself to everyone.
I have a strange 1980 W116 350 SE V8 problem. when car is cold it does not accelerate well, cuts out and then struggles to start. When it does drive it does not pull and splutters all the time. Once its fully warm it then drives ok with and occasionally will not respond to the accelerator. This points to warm up regulator. I did the following over a period of time before getting to WURb.
1. New coil and new plugs.
2. Checked and changed rotor.
3. Changed fuel filter and fuel pump.
4. Warm up regulator cleaned reset.
5. Replaced Warm up regulator with used one cleaned and reset.
6. Removed tank cut open cleaned and welded back together.
7. Fuel accumulator is relatively replaced with new part a few years ago.
After all this problem still persists and only goes away after putting in fuel line cleaner fluid. The car functions fine for a few days and weeks maybe.
8. This weekend found two used WUR with no change when cold and again after putting in a bottle of fuel line cleaner car functioned well, accelerated etc.
Help....dont know where to go from here.

Hi William,

if I was not around any more, this website would also not exist. So yes I am still here and I do run 7 workshops on D-Jetronic and K-.Jetronic this year.

You talk of WUR but you claim a 1974 350 SE. That should have D-Jetronic and no Warm Up Regulator but a MAP sensor.

Viele Schraubergrüße - best regards, Dr-DJet Volker

Then it would be wise to open a new thread as this is a completely different story. And add there also please whether US or standard engine.
