about 12, 13,000 RPMS.
1800 or so
You should be around 2200 - 2500 rpms.
9500
You have a vacum leak. A big one. Check all your hoses. Idle should be under 1k rpms
Well it should be going about 4000 rpms
the rpms should rise and then drop no more then 500 rpms when the fan on the radiator turns on and then off.
try a tach
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.
It would depend on the gear ratio and transmission. stock tires 235/70r16: auto(O/D) with 3.55 gears =2160 rpms auto(O/D) with 3.73gears = 2270 rpms manual with 3.73s = 2360 rpms
500-1200 The computer will decide.
Oil pressure ( Minimum ) 1000 RPMs 6 LBS 2000 RPMs 18 LBS 4000 RPMs 24 LBS It must have at least that much oil pressure at these different RPMs to LUBE the engine. If it has 80 LBS are more then the oil pump check valve is not working correctly
