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.
A lack of acceleration is also a danger signal. All of these are showing a difficulty with not enough energy to have engine work properly. Changing the spark plugs is a way of assuring top efficiency and performance. The misfires that may occur will increase exhaust emission as well as harm gas mileage.
