any lights on your dash flashing? check all the fluids and spark plugs to make sure their in good condition. are you using the recommended 91 premium fuel? 87 will do fine but results in less power. also 91 gas usually has more cleaning agents in it. also try seafoaming the engine, manifold and fuel tank.
