I am pretty sure that it is computer controlled. There is probably an input to the computer that is out of whack. There may be a code stored it the computer that may elude to the problem. If an input like a mass air flow sensor or crankshaft sensor is going bad, it will report false data to the ECM and it will make an incorrect adjustment that will flood or starve the fuel/air mixture causing a stall.
easier, try to clean or maybe change the IDLE AIR CONTROL VALVE, located near the throttle body, where the air intake is, it's not difficult, it's attached with 2 bolts, then it's like a pintle with one spring, check the spring shape and replace the unit with a new one, this valve controls the air flow to your engine and if it goes bad , the RPMS are likely to be low and also stalling could occur right away when you start the engine or suddenly too
7 degrees idling @ 500rpm (650 for USA)
up to 500rpm so about 200 hp
Check the air supply, make sure the filter is clean and that the intake is clear.
How low is low. If you have the Multiport Fuel injected engine it is normal for it to idle just at 500rpm give or take 50 prm. Anythign lower and you have a problem.
Easy!! Put it on the neutral position. Press the gaz pedal to the end. When it goes cut off note the RPM. It's the RPM cut off minus 500RPM
On most vehicles there is a screw located on the throttle body, it is the idle control. Sometimes it is cover and sometimes not but most times it is recessed. Tightening the screw will cause the idle to drop as it is cutting off the airflow through a secondary passage in the throttle body, loosening the screw will raise the idle allowing for more air to pass. Sometime in warmer or colder weather the airs density can be too high or low for the vehicle to idle properly and this screw must be altered.
Theoretically a 40x could spin up to 20,000 rpm at it's maximum, although this would very rarely happen. 1x CD-ROM drives spin up to 500rpm
Found one DC motor having small sparking,but the commutator is light and dark bar pattern.commutator is round. We 500kw dC motor operted at 500rpm with 480Amp's .The DC motor full load current is 1050Amp's. Why the commutator had small spaerking.
To answer this question you would need to know the geometry of the fly wheel. A 6' flywheel would have a lot more energy than a 3' flywheel. If the weight was distibuted away from the axis and towards the circumference (as it is in most flywheels) this would also increase the stored energy.
Could be timing. Could be a gasket seal. Or in my case, was blowing black carbon in my exhaust, was burning to much gas. Clean the spark plugs or replace them entirely, check you mass air flow sensor, and in my case I need to replace my air intake as well.
If you fluid it to low it could cause it. Check it while the car is warm to get the best reading. ** Already checked the fluid, it's fine. I'm wondering about the torque converter because it seems to only do it at the bottom end of a gear, almost like it's having trouble deciding what gear to be in and the engine RPM's jump back and forth about 250-500rpm while it's doing it.
Unless that is an extremely radical 350 it shouldn't be idling at 1500 rpm in the first place. It should idle around 800 rpm and drop maybe a couple hundred when put in gear. If you are having to idle it at 1500 to keep it running you do have other problems. Could be timing, vacuum leaks, or a poorly adjusted carb. I'd start with those first.
