They should all move together. Sounds like you need to balance them. There is a screw or allen head bolt on the tops of each throttle body. Turning this allows more air through. You can listen with a piece of pipe or easier get a carby balancer. You can get one from england for about half the price as in Australia. I bought one 2 months ago for about $40
