Some Dodge Journey owners report experiencing slow acceleration and high RPM issues despite recent fuel injector, spark plug, and throttle body services. These problems may be attributed to underlying misfire issues that persist even after maintenance. Additionally, if the check engine light is illuminated, it is crucial to check for trouble codes in the powertrain control module, as these codes can reveal specific performance-related problems. Fluctuations in fuel pressure can also contribute to misfires and poor acceleration, making it important to ensure that fuel pressure remains steady at higher RPMs. A dirty air filter may further exacerbate these issues by restricting airflow, leading to engine performance problems. Furthermore, recent fuel pump or tank services could be impacting the vehicle's performance, potentially causing misfires and affecting the fuel mixture. For a thorough resolution of these concerns, consulting a mechanic or dealership for diagnostics and repairs is recommended if issues persist.

Some Dodge Journey owners report experiencing engine power loss and acceleration issues despite having their vehicle serviced at 60,000 KM. These problems may stem from several underlying causes, including potential transmission issues that prevent proper acceleration even at high RPMs. Additionally, a dirty throttle body can lead to slow acceleration and poor engine performance, often accompanied by erratic idling and engine sputtering. Owners may also find that spark plug issues contribute to these acceleration problems, making it essential to check their condition if they were replaced during the last service. Furthermore, a pinched exhaust pipe can restrict exhaust flow, resulting in a lack of power and jerking sensations during acceleration. Lastly, problems with engine timing, influenced by crank and cam sensors, can also adversely affect performance. Given these potential issues, it is advisable for owners to consult a mechanic for a thorough inspection to accurately diagnose and address the cause of the power loss and acceleration concerns.
