The idle speed is computer controlled and is not adjustable. If the speed is incorrect, there is a malfunction with the idle speed motor, a sensor, or wiring.
Check the timing and check that the cable to the accelerator is adjusted correctly.

If your 1992 Voyager does not seem to drop into the proper RPMs so that you are running at 5000 RPMs at 65 miles per hour, the timing belt might need adjusted. It can also indicate the idle is set too high.
2 rpms? Your automobile engine probably runs around 2000 rpms. At 2 rpms the engine would stall and stop. However, many automatic transmissions jerk a little bit as they shift gears. I suspect this is what is happening to your Pathfinder.
Poor driving habits, poor air intake, improperly adjusted fuel pump, excess operating RPMs.
There were 3 engines available: 225ci "slant 6" I-6, 100 hp@ 3600 rpm/ 170 lb-ft@ 1600 rpms 318ci V8, 150 hp@4000 rpms / 255 lb-ft@1600 rpms and a 360ci V8 rated at, 170 hp@ 4000 rpms / 280 lb-ft @ 2400rpms
you need to have the bands adjusted.
My Del Sol was doing the exact same thing. We discovered the timing belt was off a notch. Also after we adjusted the timing belt, it began getting better gas mileage.
The 1999 Yamaha Virago XV1100 LCÊdid come with a rev limiter. This means that the RPMs of the vehicle won't go over a set limit.
Check you spark plugs. Probably going to need to replace them.
I have a 95 civic LX. I adjusted my idle speed and caused my car to jump rpms from 500-2000. I had it set to high. Once I adjusted it lower, it idled perfectly. It could also be your 0 2 sensor
Start the engine and use a can of WD40 to spray any suspected hose. When you hear the engine change RPMs, you have found a leak.
