I have a same problem with my 300 TD and it could be a couple of things.
1. The systems in that year operate on vacumm, so you might have a leak in one or more lines. 2 There is a fuel cut off valve that might be sticking. 3 You might want to check your vacumm pump. I aqm not sure of what the reading should be but bet guess around 20 to 26 inches. Good luck

Likely a vacuum leak or a faulty shut-off valve.
