My 92 626 will blow crazy when it reaches a speed of 35-40 MPH. It doesn't do it all the time and seems to onoy do it when the car is first driven in the morning. Any suggestions.

sounds like a posible choke problem.
test the choke pull off for vacuum, and test the carb heat for continuity.
A good way to tell if it is the choke is that when not under load the engine will gallop as the rpm is increased rather than revving smoothly.
If you have fuel injection, there are a few vacuum tests you can do also.
