Chris, you bring up an interesting thought about the pre- heat hose connected to the air filter box. However, most of the past winter I never had it connected because it was all busted up and I just ripped it all off. Then just about a month ago I picked up a new one and slipped it on.

Why this is interesting to me, is that I didn't have this problem through out the winter unless it had warmed up outside. I recall last February I had the stall out and at that time changed the fuel pumps. It went away until this spring when the outside air started getting warmer and I didn't have the hose on at that time. I seem to think that when it was very cold out the car rarely missed a heart beat. So I wonder if the air mass is cooked or has been form some time.
Where is the air filter box thermostat??? I would like to check it out.

I have another air mass meter on the way from Stranbergs auto yard in Wisconsin. BTW they are big on Volvo's so if you need something you should try them.


Thanks
Judd
