When I accelerate I hear a ticking noise?

With the engine, the tapping noise is either lack of oil lubrication in the top of the motor (or loose valve train hardware like lifters) or due to engine knocking (small misfires). In the axle area, this type of noise can be caused by damaged CV joints, or even a brake rotor that is warped.

If a clogged fuel injector continually struggles to disperse fuel to the engine, a time will come when it misses the fuel supply completely and the engine will misfire. The misfire will easily be felt while driving, and often requires immediate repair by trained automotive repair specialists.

Will a bad fuel injector throw a code?

Diagnosing a Clogged Fuel Injector

One of the obvious symptoms of a clogged fuel injector is the lighting up of the "Check Engine" light in your dashboard. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes.

What does diesel injector rattle sound like?

Injector “rattle” can sound like noisy valve tappets, or rapid machine gun fire. The injector could be fouled by contaminant, or is seizing due to inadequate lubrication. Excessive fueling could be causing detonation inside the combustion chamber, instead of smooth combustion.

A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on. Once that light is on, it's time for a trip to the repair shop.

How do I know if my fuel filter is clogged?
