I have a 940 automatic volvo with 156000 on clock. This problem has got me stumped and the mechanic is scratching his head too. The car is dying at intermittent times. It started with just loosing power when the gas was pressed but it would pick up and carry on with no problems. This happened occasionally for a couple of days then had no problem for weeks. Last week it died and stopped but restarted and managed to get home with no probs. The a few days later it started this stalling again but this time after about 5 mins of driving erratically I pulled up and the engine died. When I went to restart it , it started fine but as soon as I put it in drive and put the gas on ,it stalled. It would idle but sounded a bit like not enough fuel was getting thru but when it was reved it sounded fine. Yet the minute you went to move it stalled. I did find the air hose loose ealier in the week and thought that might be the problem but I think it was coincidence. From reading the messages I am thinking fuel pump relay or air hose rip. I cannot understand why it goes like this then will be fine after a nights standing. It is now at the mechanic but is behaving fine, no sign of the problem. It happens at no specila time of day when hot or cold or wet, no rhyme or reason. Any ideas would be great as I do not know where to start. Thanks CLare
