Dying on accel; idle and slow accel OK 900 1991

Posted problem previously, but now have more diagnosis on my 1991 940 turbo.

Started cold (-5 Deg F this morning) and test drove using heavy acceleration letting turbo kick in and OK.

After warming up wanted to die (I mean back fire and really die) on heavy acceleration. Happened about the time turbo kicked in. Drove for half an hour and seemed to get better. If give gradual accel, even with turbo kicking, it was fine; but heavy accel, runs rough.

I checked vacuum hoses and air intake hoses (unless interior vent vacuum problem), and can't find any splits or disconnects. Could this have anything to do with temperature a sensor or the spring door watchamacallit in the air filter box?

Any help appreciated. This is a new one on me.

Gary
