It's weird because I feel like I'm starting a whole new powerband. Like one burst of power, of course is at 750, the next at 4400, the next at 5700.. But my butterflies are always open..
Is it all in my head?
with the engine at operating temperature. pull the vacuum hose that connects to the dashpot. the arm should drop. this will tell you if they are working properly.
