Q why is my engine revving in park

When an engine unexpectedly revs while in park, several factors could be responsible. A common culprit is a malfunctioning idle air control valve, which regulates engine idle speed by managing air flow, and when faulty, can cause erratic engine behavior. Vacuum leaks in the intake system can also lead to higher than normal revs by introducing extra, unmetered air into the engine, disrupting the air-fuel balance. Additionally, issues with the throttle position sensor, which communicates the throttle’s position to the engine control unit, can result in abnormal revving as the sensor’s incorrect readings lead to improper air-fuel mixture adjustments. Regular maintenance, including inspection and cleaning of these components, can prevent or resolve such issues. Always consult with a professional mechanic to diagnose and address specific problems accurately.

The 4.7L Dodge engine, first introduced in 1999 for the Jeep Grand Cherokee and later found in Dodge Ram, Durango, and Dakota, has had mixed reviews. Its design aimed at providing a good balance between power, efficiency, and emissions. Early versions faced issues with durability, particularly with overheating, head gasket failures, and timing chain problems. However, improvements were made in 2008, enhancing its reliability and performance. When well maintained, newer versions of the 4.7L engine can offer a decent lifespan and satisfactory driving experience. Owners should adhere to regular maintenance schedules and be mindful of known issues. In comparison to its predecessor, the 5.2L V8, and other engines in its class, the 4.7L strikes a good balance for those prioritizing a blend of performance and fuel efficiency in their trucks and SUVs. Overall, while it may not be the top in its class, with proper care, the 4.7 Dodge engine can be a solid choice for moderate use.
