What problems can be caused by a faulty Fuel Air Filter?

Engine doesn't start up and/or cuts out when running

The engine doesn't start up very easily and will often not start at all. When it is running it can cut out completely without warning.

Check Engine warning light showing on dashboard

The dashboard warning light showing on this page (or one very similar, sometimes a slightly different shape or colour) has appeared on the dashboard and doesn't go off when the car is running.

Engine is rough at idle speed

At idle speed the engine sounds like it's about to stall, it improves when the accelerator is pressed down but when idling in traffic it sounds like it's struggling to run properly.

Car acceleration or performance is not as strong as normal

When putting your foot on the accelerator the car does not respond with the same urgency of acceleration. It feels like there is a lag between putting your foot down and the car accelerating, when it does accelerate it feels like a much slower change in speed.

Engine is running rough

When the engine is running it does sound like it would normally, it can sound like it's struggling to keep running or produce strange noises that sound like it's not running in time with itself.
