My vehicle has noticeable or excessive smoke coming out the tail pipe, what does that mean?
If the smoke is gray or black in color it typically means the vehicle is running rich (to much gas and not enough air). If you only have experienced this when the car is started it is typically an issue with the settings of the fuel injection system. If you get black smoke all the time, there are additional problems with the fuel injections system that need to be checked. For example, oxygen sensors, map sensors, fuel injectors, fuel pressure regulators, air filter, etc. If this condition is allowed to continue, it could cause damage to the catalytic converter as well.

If the smoke is blue in color it means the vehicle is burning oil. This can be caused by bad pistons and rings, damaged cylinder walls, or other internal engine damage. If the smoke is white in color it is a sign of a coolant leak or coolant being forced into the cylinders and being burned. Typical causes of white smoke are faulty head gaskets, a cracked head or broken cylinder wall.   Heading Off Problems: The more you
