Nissan Xterra idling at 4 to 6 RPM while barely exceeding 30 MPH after stopping on Nissan Xterra

Some Nissan Xterra owners report experiencing rough idling and occasional stalling at stop signs, which may indicate problems with the idle control system. Others have noted burning oil without visible leaks and rough idling when warm, suggesting possible internal engine issues or oil circulation problems. Additionally, some owners report sluggish acceleration and rough idling, potentially linked to fuel delivery or air intake issues, such as clogged fuel injectors or dirty throttle bodies. Low idle RPMs around 550-600, accompanied by cabin vibrations, could be due to improper idle adjustments or engine mount problems. Some owners have also found that checking the fast idle component for bending beyond 90 degrees can reveal causes of high RPMs after warm-up. Lastly, intermittent leaks from brake pedal operation affecting the diaphragm may lead to variable RPMs and adjustments by the fuel system. Addressing these issues is crucial for improving the idling and overall performance of the Nissan Xterra.
