Nissan Murano high idle and bounce issue with poor gas mileage on Nissan Murano

Some Nissan Murano owners report experiencing high idle and bounce issues, which can lead to poor gas mileage. These problems may stem from factors such as a faulty air filter, transmission issues, or mechanical concerns like engine timing, low compression, exhaust leaks, or worn piston rings. Additionally, underinflated tires have been noted to negatively impact fuel economy, causing the engine to work harder and consume more fuel. Ignition system problems can also contribute to rough idling and hesitation, further affecting performance and efficiency. Furthermore, some owners find that poor gas mileage can result from high idle, sluggish acceleration, and mechanical problems, with bad fuel injectors, coil packs, or spark plug wires causing jerking during acceleration and decreased fuel efficiency. It is advisable for owners to check and replace the air filter, inspect the transmission, ensure proper tire inflation, and diagnose any faulty components to improve performance and fuel economy. Seeking professional assistance for mechanical issues is also recommended to effectively address these concerns.
