Normal operating temperature 650-750 RPM it should be between 0.5 and 1
My '89 Accord just began idling like that. It turns out that two of the belts broke yesterday, so maybe your belts are on the verge of breaking. Mine has been idling like that for just a few days before the belts broke.
The spark plug gap can cause the RPMs to fluctuate, while idling. The more probable cause of the fluctuating RPMs is a bad camshaft.
This is a sign of a weak alternator or possibly a loose belt. At idle your car is running at a low RPM. The alternator is driven by the engine so it is also running at a lower RPM. When the vehicle is accelerated the engine RPMs go up. This in turn drives the alternator faster, and it is able to produce a higher voltage.r
The idle arm may be off set. The idling is set extremely high according to the RPM's stated and need to be lowered.
It is generally caused by improper valve adjustment. But can be caused by excessive RPM. On the 17.5 the intake push rod is most often the one bent or broke. Try idling down the engine prior to turning it off.
when a dozer is idling its rpm are at 90,000 to 95,000 Could be dirt in the carb's idle circuit. Maybe a vacuum leak.
800 RPM
Mine is between 500 and 600 rpm's after the engine is warmed up.
check your vacume lines by spraying them down with carburetor cleaner. if the engine revs when you spray you found the leak. also check your air flow meter it could just be dirty.
Yes - You have a vacuum leak

cause if its idling at zero rpm the motor is off ...
A bent valve(s).
Have your servo control checked
a good idle is usually at 1200 rpm. 600-800RPM
Because the efficiency of the fan and the water pump degrades at low RPM.
Most fuel injected automobiles rev when first started, most to about 14-1600 RPM, then settle down within 700-900 RPM after 3 to 5 seconds. The exception to this....On a cold start, or when the car is started for the first time (that day), the cold start will hold the RPM higher for a longer period of time. Unless your car is idling high for an extended period of time or reving above 2000 RPM, I would not be concerned. one indicator of a problem is your CEL (Check Engine Light), if it's on, you more than likely have a sensor issue and need to have it repaired.
