The fuel filter holds an important place in your car’s engine: The fuel filter filters the fuel that the fuel pump pumps. (Got that?) If the fuel filter isn’t doing its job, fuel can’t get to the engine in sufficient enough quantities to give you the performance you expect. Think about a window screen caked with mud and you’ll start to get the picture.
If the fuel filter needs changing, you might start seeing certain symptoms:
- Problems with Starting: Or maybe you Pontiac does start, but it takes a few attempts.
- Stalling: Your definitely don’t want your car to die at the wrong time. Pay special attention if you stall while idling at a red light or stop sign.
- Excessive Vibration While Driving: If you feel the engine idling roughly or lurching forward, that can be a sign of a clogged fuel filter.
- Rough Slow-Speed Cruising: Highway cruising might be fine, but struggles at slower speeds could mean you need to replace your fuel filter.
