Dodge Journey slow acceleration and high RPM issue despite recent fuel injector, spark plug, and throttle body services on Dodge Journey

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.
