White exhaust smoke often happens when an engine burns coolant that has leaked into the combustion chamber. If it continues well after start-up, then you may have serious trouble. This is a common sight when cars, even modern ones, are first started in the morning. The remedy is to repair the fuel injectors.ĭoes the exhaust smoke quickly dissipate after leaving the tailpipe? If so, it is probably the result of condensation building up within your car’s exhaust system. The gas is drawn into the combustion chamber and mixed with a predetermined amount of oxygen to optimize the efficiency of the burn or combustion event. Leaky or clogged fuel injectors: Fuel injectors are small electro-mechanical devices used to spray a predetermined amount of atomized gasoline (a mist of gasoline) into a vehicle’s intake manifold, which is directly in front of the intake valve. The remedy is to replace the fuel pressure regulator. Too much pressure may result in over-fueling, which can make your engine run rough and deliver poor fuel mileage, among other things. If it falls too low, there may not be enough fuel reaching the engine to start it. If the regulator is on the fritz, the pressure will fluctuate outside of the system’s specified range. Two of the most common reasons for this are a malfunctioning fuel pressure regulator or leaky or clogged fuel injectors.īad fuel pressure regulator: A vehicle’s fuel system is designed to work within a specific range of pressure, which is controlled by a fuel pressure regulator. If the problem persists, it’s an indication that your vehicle’s air-to-fuel ratio is askew – specifically, it is burning too rich or more fuel than air. The remedy is simple: replace the filter.
