Can anyone tell me some symptoms of a bad EGR valve?

My 86' Ranger acts like it is running out of fuel when you accelerate (Only happens at normal operating temp); I have just replaced the fuel pressure regulator and that wasn't the problem. It also tries to backfire through the throttle body.




Thanks for any advice anyone can give.

EGR allows exhaust gas to be delivered into the intake to stabilize combustion temperature. So I suppose if the valve is malfunctioning then too much inert exhaust gas can be delivered to the combustion chambers.
