Having an issue with an 87 300TD, it stalls out at low idle speed continuously, upon startup and when driving and coming to a stop. I flushed fuel system (flushed tank and cleaned screen, used compresed air in hard lines, changed both filters four times since stalling began), problem persists and worsening?

 

Thanks for the reply! Ok i pulled off vacuum hose off of the round plastic white piece on top of pump after i started car and it still stalled after raising rpm then taking foot off. Did i pull the correct vac hose off?

 

Thanks again, i guess i did have the correct vac hose, still no diference is noticed when hose is removed. Any more bright ideas? Injectors possibly? It acts as though it is starved of fuel when idle is lowered suddenly, and then stalls out.

 

If this is consistent you probably need to take the injector pump in to a reputable rebuilder,and have it checked out. I doubt that it is injectors, they don't typically all go out at once. Before taking your pump off and checking it you might try checking all of your return lines, make sure that they are tight and not corroded. The rubber hoses between the injectors, and the lines all the way back to the tank
