Hello Typically the most common cause of this is a blown intake manifold gasket - somewhere around number three or four cylinder. With the engine running lightly spray some wd40 or similar on the gasket joint and if the engine sound changes - the gasket is blown.If it doesn't alter the next step is a compression test to confirm if there is a mechanical fault.regardsMechanic Martyn
