Naturally casein-free foods are of vegetable origin. Fruits and vegetables are casein-free foods, and nuts can also be considered in the diet if there are no restrictions. However, some processed foods containing fruits, vegetables, or nuts may not be casein-free foods. Casein is an excellent binding agent and may be used in spreads, dressings, and other processed products.
Engine misfire is the first sign of poor spark. Basically, the spark plugs are firing poorly or incorrectly, so combustion is not ideal or controlled. The sputtering or chugging of the engine is a sure sign of misfire, but a noticeable loss of power or a check engine light due to raised emissions are also symptoms.
Attempting to remove the spark plugs from a HOT engine may cause the spark plug threads to seize, causing damage to the cylinder head threads. Remove spark plug boots by first twisting the boots back and forth until they move freely on the spark plug and then pull off while holding the spark plug boot, not the spark plug wire (if equipped).
