Good news... I sprayed that port with carb cleaner and got much better vacuum. I unplugged the computer and plugged it back in after a few minutes and it still bogged and had hesitation but not as bad. I later drove it 5-7 miles and it ran like a top so I decided hey lets hit the highway. I made it about 200 feet down the ramp and it started gagging and bucking. BLAH at least its intermittent which tells me after running 4k miles in the past 5 years it probably has something stopping up a port in the carb every now and then.
