Just a thought here,your gas cap.The vent hole could be plugged,causeing pressure buildup,not venting?Just a long shot.Crack your gas cap loose and see if this sucking continues?
I have forgot to mention that I have the crub idle set at 950 RPMS but after I run the car awhile, get nice and warmed up that it will not idle down to 950 but stays around 1100 RPM. I'll ease the clutch out and bog the motor to "kill it" so the idle will drop down to 950 RPM when at a stop light. There is some weird stuff happening here.:angry7:
