I had a vacuum leak. main line that goes from the bottom of the circle erg junction thing to the rear of the intake, little metal hose that sticks out from the rear of the intake/head. I removed and replaced the busted line, and now i have a issue where it will not go faster than 80MPH and its at about 3500-4000 RPMS. sounds like it has a slight bogg? not sure i just know that it doesn't have the power and it SUCKS. I need help...
