You are so at ease that even if you board your car at 7am, you’d be able to get to work on time. One day, 7am, just like any other day, you board your car and started up the engine – poof! Not starting. You just keep on turning those keys and trying to rev to warm up the engine, but the engine seems to be having a hard time starting up. Consequently, you were late for work, for the first time ever since you had that car.
If you're having a car start up problem, you could blame a dirty air filter because not enough air goes through the engine
This kind of problem could be a result of a dirty and neglected air filter.

Uh-oh – seeing the “service engine” light can cause us quite a panic. First thing we’ll worry about is the cost of having the engine repaired, or worst, replaced. We can be quite advanced thinkers especially when money is involved – but don’t fret too much. This service engine light might have lit up because of a dirty air filter. Why? Because with a clogged air filter, the engine receives insufficient air that it needs, therefore resulting to deposits inside the engine.
So next time you see this light, don’t press your panic button on just yet – check your air filter first if its dirty and if it is, clean it or have it cleaned by a professional.
