On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.
On the 3.7L V6 and 4.7L V8 the camshaft position sensor may fail and cause the engine to crank but not start or it can cause intermittent stalling. A failed camshaft sensor will require replacement.
A surging or bucking during acceleration can be caused if the distributor is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear can cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.
The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops. There is also a revised vacuum check valve available to address this concern.
The track for the power seat may need to be replaced if the seat rocks when the vehicle accelerates or slows down.
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.
If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the "OK to start" signal.
On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.
If the vehicle will not shift into, or out of four wheel drive, and the "Serv 4WD" warning light is illuminated, the front axle disconnect actuator may need replacement and a power module (TIPM) may need a software update.
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.
Battery acid can leak on, and deteriorate a vacuum hose for the speed (cruise) control system. If the hose becomes loose or leaks vacuum, the speed (cruise) control will not function.
