Revs on a Vauxhall Zafira can fluctuate due to several factors, including issues with the engine management system, problems with the throttle body, or a malfunctioning idle air control valve. Additionally, vacuum leaks or fuel delivery issues can affect engine performance, leading to unstable RPMs. Regular maintenance and diagnostics can help identify and resolve these problems. If the issue persists, consulting a professional mechanic is advised.

What cause your riding mower to idle up and down when am mowering?
When mowing it will idle up and down because of the amount and thickness of grass you are cutting. This is because the blades will struggle cutting thick grass so the engine needs more revs to keep the blades running at a constant speed and that is also why your mower may slow down because it has used the majority of revs to cut the grass and their are not many revs left to keep the wheels spinning The up and down revving could also be caused by a dirty/clogged air filter.
