Hello everyone,

I have run into an intresting problem with my 1992 940 Turbo Wagon. Today it was very hard to start, infact it would not start for several tries untill i floored it. When it did finally catch, it had an extreemely rough idle and refused to hold it. I finally worked the courage to put it in gear and took it about halfway around the block. Whenever starting from a stop it is very reluctant to go, it makes a type of shaking when first accelerating. The turbo will not engage (the boost gauge gets into the white) or will engage a little and the shaking starts again and the engine wants to die. I poped the hood and found a line from right below the throttle body (the line attaches to the intake manifold) had broken off at the temp sensor (well, i think it is) I reattached it and that seemed to work about half way down the block where it started again. I have recently had the air mass sensor replaced and the car did exhibit similar problems befor replacement.
Perhaps the line is too short now and is constricting airflow? Or cracked?
Well, if you have any suggestions, they are much appriciated.
TIA,
Taylor Jones

Why an air-mass meter, let me guess the clamps broke and you couldn't secure it to the filter. You got taken, go to Home depot next time and buy some mini-C-clamps and screw it down.

You need to go thru all of your intake manifold side vac-hoses and replace every single bad and rotten one.
However, first that little silvery-can [on the front-facing side of the intake manifold] with a small vac-hose on the front and the fuel-manifold and fuel return line at 9 and 12o'clock is the FUEL-pressure regulator.
Fix/replace the vac-hose to the intake manifold first. That should at least start and run the car.

Most likely you have multiple vacuum leaks from hoses you can see and those you cannot.

Get them all inspected and/or fixed then assess your problems.
