The most likely cause is using gas with a lower octane rating than recommended. Check your owner's manual. Another cause is carbon buildup around the valves keeping them from closing properly. A couple of treatments with a fuel additive may help. Follow the directions and make sure you use it on a full tank of gas. This is especially important on Turbo vehicles because of the added air that is forced into the combustion chamber. High test fuel = better performance. Other reasons for this would be ignition timing incorrect, carburetor in need of adjustment or fuel injection system malfunctioning, improper or damaged spark plugs or wires, worn or damaged distributor components, faulty emission system, or a vacuum leak. Knock sensor failures can cause engine knock on acceleration.
