How long does it take to warm up a car at 2000 rpm?
Do not I say! it is only 2000 rpms when i start the car when it is warmed up is normal… i was worried how long it would take to go from 2000 rpm to under 1000 rpm when its really cold out and the engine takes longer to warm. now it takes about 5 minutes and its only about 58 degrees…
What should the idle RPM be on a car?
Your engine should normally get to around 700 RPM after you start the vehicle, depending on the model. If your idle is way off and you have one or more of the problems listed above, then you will want to diagnose the issue right away.
Is the car supposed to idle fast after start up?
All modern cars are supposed to idle fast just after start up. Yours seems to be doing what it is suppposed to do, only with a bit more rpm. 2K seems a bit high, but the tach on your insturment cluster is not as accurate as a shop tach hooked up to the motor.
Why does idle speed drop during cold startup?
If the idle air control valve did not compensate for these, the idle speed would drop when certain accessories are used. In severe cases, the engine may even stall. The idle air control valve is most important on a cold startup. Problems with the idle air control will be most obvious during this time.

How does a Smiths chronometric mechanical tachometer work?
It uses a computer-controlled stepper motor to recreate the distinctive “tick-tick-tick” movement of the old Smiths Chronometric mechanical tachometer from the 1960s. Above 5000 RPM, the needle returns to a normal, smooth sweeping motion. It’s a very cool feature that vintage racers really appreciate.
Why do shift lights fire randomly on my tachometer?
Shift lights will fire randomly, sometimes even at idle. SPA tachometers seem to be particularly sensitive to these spikes, but Auto Meter and Stack tachs seem to be much less affected. The fix is to add a simple 47k Ohm resistor (1/4 watt, 5% to 10%, rated to 500v) in the RPM signal wire from the coil to the tach.
Why do the shift lights always read higher than the RPM?
These additional little spikes are read by the tach and shift lights as another firing of that cylinder. Since the spikes are random, they confuse the tach into bouncing up and down, usually reading higher than the actual RPM (but almost never by a constant factor). Shift lights will fire randomly, sometimes even at idle.
