I just purchased a 94 850 turbo wagon a few weeks ago. The check engine light came on soon after and it showed codes 241, egr system flow fault, and 315 Evap system fault. Around this time the car would stall out very intermittantly, could not tie it down to any specific scenarios- I would just be driving along fine and the engine would just cut off and the dash lights would come on. I would let the car rest for about 15 seconds and it would start back up and it would not stall out again right away- maybe a day later or mabey 10 min. later, very intermit, and unpredictable. Upon further investigation the vacuum hose to the egr vale kept working off- I secured it, and I also fixed a vacuum leak on the large hose that attaches to the throttle body. I also replaced the fuel filter and checked the spark plugs (seem fine).I also checked the battery grounds and connections and all seem fine. I cleared the codes and the check engine light has not come back on now for 3 days and I thought I had solved the problem and was pretty proud of myself- but the problem has reared its ugly head again. This time the car has stalled out twice soon after starting the car driving home from work, on a straight bit of road going about 35-40 mph (same deal the car will start up again and drive ok after 15 sec or so), and the check engine lights have not come back on. Are there any red flags to what this problem may be? Fuel relay? I am new to Volvos and have found these boards very informative. Any help would be much appreciated- Tony.
