my '72 250ce keeps stalling help !!

[w114]

i have been having the same issue for a while, its an inter mitten fault the car starts normally, but once running it jurks and wants to stall, but keeps running,for a few minutes then cuts out. if i try to drive the car, it jerks as if i am press the gas and taking my foot off repeatedly. i have changed lots of different things, i have changed the points for an electronic start system, i have changed the plug leads, i have re-furbished the injectors, i have changed both regulators, and recently the bosch fuel control units, which are located by the fuse box, i have taken it to a couple of mechanics and non are able to see the issue, the only thing left is the fuel pump. to change, so i was wondering if anyone has had the same or similar issue,and can shed some light on my problem, i have had the car for 8 yrs and do not want to sell the car, love it it much, so any help is appreciated cheers.

Check for a collapsed fuel pipe, also overpressuring?

I have someone after a fuel pump (I'm breaking a '72 w114 250ce) but if you need one and it falls through get in touch with me

hi mate its the same guy ... i sent u a txt earlier. how are you doing? wanted to ask about the cpu for the car ..the silver thing in the passenger foot well would that cause it ? and if you have it on your car i would be interested in it as well..

hahaha phone battery dead!

yes i have the ecu its off the car as someone wanted it and didnt pay.

he offered £45 for that (theyre rare), could do that and the pump for £75 but couldnt go any lower, does that work for you?

you said to check for Check for a collapsed fuel pipe, also overpressuring? would any of these be inter mitten? and overpressuring where do i check for that?
