Fw: '83 URQ Surging


I still have not had the chance to diagnose my boost problem. However, over
the past couple of days a new annoying problem has developed. The car starts
and runs fine. When the car warms up a little, it occasionally surges under
acceleration when the car is under normally aspirated conditions. When the
car goes into a boost condition, the surging stops and the car performs as
close to normal as it has. ( still have a high boost problem)

Any suggestions when I go out to look at it.
The first things I am going to check are the air bypass valve and the closed
throttle switch.
