750 to 900 rpm Whem it is warm, cold start 1200 to 14000 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.
when u first start the car it will idle high, around 1.5 rpm to 2 rpm. when its warm up it should idle between 700-1000 rpm
cause the coolant temp is low , automobiles tend to do that when there cold
it only studders at low rpm it runs great at high rpm or accelerating only at idle and take off rpm
rev limiter will only let the RPM's get so high then it cuts back
RPM is short for Revolutions Per Minute. It is the measurement of how many times your engine is rotating each minute. As you accelerate, your RPM will increase until the next gear is selected, lowering the RPM. RPM is the whole reason for transmissions: if there was only one gear the RPM would get so high that the engine would become damaged. By shifting into higher gears, the RPM is lower and you get better gas mileage.
Flooring the gas petal.
Have your servo control checked
Because your foot is on the accelerator
Your throttle cable, needs to be adjusted.
a dining sound could be lose nuts on the exhaust
Yes, but it depends on what "high" means. It shouldn't race, but 200 or 300 extra RPM would certainly be normal. The other thing to consider is the time it takes for the RPMs to go back to normal.
Something is out of balance, maybe the water pump is on its way out.
If it's a stick, it sounds like the clutch or clutch componets.
mine does this. when the motor warms up & the choke does its job it idles lower as opposed to fast idle from a cold start. when you start it again its already warmed up and the choke does not need to adjust itself. for 2nd gen 750 rpm is normal at operating temperature.
No, but why would you?
if the engine is cold the computer says I'm cold so rich up the mixture and speed up the engine via TPS. then once the engine warms up another sensor tells the computer it has warmed up and decrease the TPS signal slowing the RPM down.
The rpm required for an alternator will depend on the result that you want. At the very least, you will want 1200 rpm. The rpm's can go as high as 5000.
vacuum leak. my 95 Monte Carlo did it. once in a while it would race to 2500 rpm then settle down like normal. not easy to find , but a cheap fix.
It is normal for the idle to be this high on a cold engine immediately after it is started. It should drop back to 1,000 or less in a few seconds. If not the fast idle solenoid could be bad.
it should be you T.P.S.. throttle position sensor that does that some time when it goes bad it will idle at higher r.p.m.s replaced it.....
cold engines hve high idles because the pcm is dumping fuel into the motor in order to increase engine operating temperature. when speified temperature is reached, the amount of fuel is decreased an the rpm drops down to the lower idle speed
