Have a 94 850 non-turbo. In January came back from holidays car had not been started for two weeks when tried would not start. Read through posts on the Brickboard. Was finally able to get the engine to start but would die when driven. Disconnected the hoses from the Idle Control Value and was able to drive but very poorly. Ended up replacing the Idle Air Control Value and the relay (runs both the fuel pump and the IACV). I first replaced the Idle Control Value after which it started right up and ran great. A week later since I had already ordered the relay I put the new relay in. Everything was good until today. Wife started today ok, drove a few miles and engine died. Believe at this point when she tried to restart engine was flooded. I held throttle up but could not get the engine to run. So I thought maybe vacuum leak from EGR or Vapor Canister or other so I disconnected and blocked off all vacuum leads going to the intake manifold. It was then when I was disconnecting and blocking the hoses that I noticed that the hose with the flame trap was dripping oil. I took off the air supply hose from the air cleaner I found that the exterior of the hose was wet with oil as well as the inside, which was also wet with oil. The aluminum throttle chamber and plate (both sides) also had oil on it. So I used carburetor cleaner to clean out the oil in the chamber and carb cleaner and WD-40 to clean out the IACV. I then looked at my oil level and it is down a quart of oil from the last oil change one month ago. I have taped the inlet hole and left unattached the flame trap. Having done this engine starts right up and runs/drives good. I plan to leave off the flame trap hose (which has gas coming out when engine running) and put a Ziplock bag (with opening to let pressure out) to see how much oil comes out. In doing research I find that the flame trap is connected to the OIL TRAP. So the question is could a defective oil trap cause the engine to stall and not restart? Or is it a vacuum leak through the EGR or Vapor Canister or other? If I am able to hook up all the hoses and the engine starts and runs good and I get oil in the Ziplock then I think it is the Oil Trap. If so how do I fix it? Thanks for the help! BDV
