Quote, originally posted by Faultline Â»I have had bucking or surging issues before, but it has been for different reasons. There is about a half inch hole on the Throttle body that is capped off or plugged, that when it tears, air escapes, and it messes up stuff.if yours is plugged make sure it still is. Sometimes I have simply taken my ground cable off the battery for a couple of minutes, and it resets the computer to clear things up. This car doesn't have that 1/2 hole on the throttlebody for the PCV system. My breather port was part of the stock intake, just have a breather filter for the valve cover. Although there was a possiblility of a vac leak on the catch can which was found. It has been removed for now.
