What Causes a Van to Shake at Idle?

1 Answers

The reasons for a van shaking at idle may include: faulty spark plugs or ignition coils; incorrect valve timing; uneven cylinder compression; poor valve sealing leading to air leakage; inadequate fuel pressure; clogged/leaking fuel injectors; leaks between the cooling system and cylinders; or a malfunctioning mass airflow sensor. The mechanism of idle shaking: Changes in the gas force within the cylinders (variations in one or several cylinders) cause an imbalance in cylinder power output. This results in inconsistent horizontal forces on the pistons during the power stroke, creating an unbalanced moment that tilts the engine laterally, thereby causing engine shaking. Any fault that alters the gas force within the engine cylinders can potentially lead to idle shaking.
