My 1990 240 wagon is in love with my volvo shop

Since Feb. I've had stalling problems with my 1990 240 wagon. The mechanic diagnosed the problem first as the air mass meter and replaced it. A couple of months later the stalling begins again. The problem still persists even after a friend of mine replaced the distributor cap and coil. The mechanic has diagnosed the problem as a million things (crank angle sensor, bad spark plugs, exposed wire to the coil, main electrican unit) none of which is the problem. After my car has been in the shop for 2 weeks now, they are NOW saying that the only thing left is to check the electrical harness. They're thinking it could be a component of the harness or the harness itself (which they're estimating would be around $800 to fix). I'm just wondering if anyone out there has any advice on this problem. Even after the mechanics replaced the air mass meter, I was still pulling the 'check engine' codes and was getting air mass meter problems and fuel system compensating for rich...whatever. Any adivce? I'm at the end of my rope and my checkbook with this problem.

MKy '81 245 kept stalling until I had the dealer redo the electrical harness. Cost about $1200 but fixed the problem. Prior to that I was in twice before for the same stalling problem.

My '85 had a bad air box thermostat, which caused the enginge to get only hot manifold air, which will damage the AMM.

Have they checked the fuel pumps? There are two and it seems that they will work in cold weather but not so good in summer. replace with good new parts.
