On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.
Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister. If black carbon particles are present in the LDP, replace vapor canister in addition to LDP. The purge solenoid should also be checked for debris or carbon contamination and replaced as necessary. All evap system hoses are subject to cracking and splitting causing leaks, Inspe...
Some vehicles may exhibit one or more of the following: Spark knock complaints when the vehicle is under load, various single cylinder misfire, and surge in 4th gear (around 45 mph). Our technicians tell us that rerouting the coil and spark plug wires to minimize induction effects will commonly correct this condition. If wires must cross during the reroute procedure, they must cross at a 90 degree angle.
On the 3.9L V6 and 5.9L V8 the engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

RepairPal Expert Overview:
Chrysler is recalling certain 2001-2002 Dodge Dakota, Durango, Ram 1500, Ram 2500, and Ram 3500 models because the park shift interlock system may not function correctly. When this system fails, the shifter can be moved out of the "Park" position with the ignition in the "lock" position. The ignition key can also be removed when the shifter is not in the "Park" position. Either of these conditions could allow the vehicle to roll away unexpectedly, possibly resulting in a crash. Dealers will replace the gearshift blocker and bracket assembly.
