I'm having a sudden issue with my '84 240 DL Wagon (215,000 miles). I purchased it 2 months ago and it's been running wonderfully.
Yesterday afternoon, out of the blue, it had trouble kicking over. Once it did, the idle was erratic and shook the car. I was able to rev it--and while revved, it felt and sounded normal. However, if I try to move the car at all in a low gear, or at idle, it stalls out.
There were no abnormal "symptoms" leading up to this--the car was running very well.
We did hit a pretty deep pothole a few days before the problem surfaced.
I've checked everything I could think of (even added gas in case the gas gauge had broken) and I'm stuck. Obviously I didn't check the right thing.
Any help would be sincerely appreciated.

suspect a vacume leak [possibly a cracked intake gasket] while not a common problem i have seen more than a few over the last 25 yrs working on volvo 2-7-9 series [check by spraying carb cleaner ajoint where intake manifold bolts to cyl head

Erratic idle can be caused by many things. When the car died it could very well been because the engine was running so poorly, but it also opens a whole separate door of problems. I wouldn't start there though. I'm not familiar with the model, but all engines need three things to run; spark, air and fuel. So I would suggest checking your air filter, spark plugs, wires, distributor assembly, fuel injectors, and fuel pressure. From there, specific parts that cause bad idle include emissions equipment, dirty throttle body, mass air flow sensor, throttle position sensor, idle air control valves, etc. Idle problems can be a huge headache. One easy thing you might do is start the car and go around to the tail pipe and feel the air coming out. If it comes in burst and car might be misfiring. Knowing that would be huge help in diagnosing the problem. Try feeling tail pipe air from a good running vehicle for comparison.

Idle is controlled by ICV. Either the ICV is going bad or wrong amount of Air is getting measured from Intake. I would start by cleaning out throttle body with carb cleaner to make sure that there is no air restriction in the intake system. Also check for air leak in the intake system in the same time.
If everything checks out, I would take a look at Mass Air Flow sensor (MAF)

If i had to guess i'd go to the mass air flow sensor first. Thats inline between the airfilter box and the throttle body, try unplugging this and see if you get any difference in the way the car runs. May also be time for a "tune up" wich would be spark plugs, plug wires, and a distributor cap and rotor.
