This bulletin applies to 2005-2006 Jeep Liberty vehicles equipped with the 2.8L VM turbo diesel engine, built before Oct. 19, 2007. The customer may experience a no-start, hard-start or rough idle condition. This may be caused by too much air in the fuel lines. A new filter/housing assembly is available that reduces the amount of air in the lines.
A dirty throttle valve will affect engine performance and increase fuel consumption so Liqui Moly has developed ProLine Throttle Valve Cleaner to rid the intake area of oil, resin and bonders.
This TSB applies to 2011 Mazda2 vehicles with DTC P0451:00 (fuel tank pressure sensor range/performance problem). This may be caused by water or snow entering and freezing in the atmosphere breather hose of the fuel tank pressure sensor (FTP).
