For these reasons, healthy levels of magnesium have been linked to deep, undisturbed sleep. Consequently, low levels of magnesium can contribute to frequent nighttime wakings. Magnesium deficiency has been linked to several insomnia-inducing conditions, including restless leg syndrome (RLS) and night terrors.
Scuffing is another condition that can damage pistons. Scuffing is often the result of overheating, but loss of lubrication, detonation and preignition can also be contributing factors. When an engine runs hot, the pistons swell. This reduces the clearance between the piston and cylinder walls. The cylinder bore can also distort adding to the problem.
The Nature of the Problem. Many things can cause an engine to lose power: bad timing, airflow obstructions going into or out of the engine, carbon buildup on spark plugs, bad gasoline and improper fuel burn in the cylinders are just a few. But these things don't often cause engine hesitation -- at least, not initially.
