OVERVIEW: This bulletin involves rotating all engine exhaust valves, replacing the valve spring retainer locks with a new design to increase valve rotation at lower RPM, inspecting/replacing the MAP sensor (as necessary), and decarbonizing the combustion chamber. MODELS: 2004 – 2006 2005 – 2006 (CS) (LX) Pacifica Chrysler 300/Magnum/Charger SYMPTOM/CONDITION: The customer may experience occasional engine misfire (rough running engine) during certain vehicle operating conditions. In addition, MIL illumination may also have occurred due to Diagnostic Trouble Code (DTC) P0300 – Multiple Cylinder Misfire. Various single cylinder misfire DTC’s may also be present. If the frequency of misfire is high, the Powertrain Control Module (PCM) may place the engine in “Limp-In” mode. The misfire condition may be caused by one or more engine exhaust valves that are slow to close due to a build up of carbon on the valve stem. DIAGNOSIS: 1. This condition may occur when the engine is not allowed to run at engine RPM’s that are greater than 3,500 RPM. At 5,000 RPM or higher the engine exhaust valves will rotate if not impeded by high carbon deposits. Low engine RPM’s and high carbon deposits are associated with short trip driving where the engine is not allowed to fully warm to normal engine operating temperatures. Cold ambient temperatures will increase engine warm-up time and increase the likelihood of carbon deposit build-up on the stem of the engine exhaust valve. Fuel detergent quality may also contribute to the condition; the customer may want to try a different brand of fuel. 2. Verify that the engine misfire condition is not caused by faulty engine mechanical or electrical components. 3. If the engine mechanical and electrical systems are operating properly perform the Repair Procedure.
