Like the title says the car misfires a bunch under vacuum; while it sounds like a dragon grumbling out the hood exit, was wondering if it's normal in a stock engine.. Maybe you don't hear it because of the catalytic converter and mufflers? It happens during deceleration from >30MPH, I found an FIC I'll be installing soon but wanted to make sure it isn't a faulty MAP sensor.. (Could it be engine braking?)
