I recently took off my Saleen Supercharger because i sold it, to make room for my new vortech . After i put all stock parts back on the car, the car idles and seems like its doing good, but when i drive it there is a huge hesitation before any power is produced, The car feels slower than a 1990 honda civic. When idling it revs up just fine, AC, Heater blows fine. I double checked for any vacuum leaks and found none. I used my old intake gaskets and im wondering if this could have made an intake leak, but i would assume that my heater would blow air from the top instead of the front when there is a vacuum leak.. im completely lost. I also have my spark plugs at .33 for my supercharger and a focus pump running on the stock tune. Could spark plugs cause this?
