Why does my RPM drop when I come to a stop?
This may be a sign of a failing idle air control valve. In cases where this valve is clogged or is failing, your vehicle will stall instead of slowing to an idle after the release of the throttle. I recommend having a professional replace your idle air control valve.
Why is my RPM gauge bouncing?
A less common problem is a poor connection in the RPM signal wire. In this case, the needle will usually bounce around below the actual RPM reading because it will miss some of the voltage spikes. Look for corrosion, a broken wire, or a loose connection anywhere between the coil terminal and the tachometer.
What should RPMs be at idle?
In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth. The RPMs will jump up and down, for example, or they’ll fall below 600 RPM (or whatever is typical for your vehicle).
Why does my Toyota Camry stall when coming to a stop?
Here’s a great YouTube video from EricTheCarGuy. on how to clean a throttle body. A dirty throttle body may not trigger the check engine light. So, if your stalling happens when coming to a stop, and the check engine light is on, it may be worth taking a look at it. All modern torque converters “lock”.
What causes idle RPMs to fluctuate in Toyota?
Resolved (11/15/15): It was a loose camshaft position sensor. Plugged it in and now the car runs fine. Quite often surging like this is caused by not enough air getting passed the butterfly valve in the throttle body when the butterfly is closed.
Where is the throttle position sensor on a Toyota Camry?
Your Toyota Camry uses a series of complex sensors to report what is going on to the ECU. The ECU then uses this information to adjust the timing, air fuel mixture, and more. When one of them goes wrong, it can lead to stalling for sure. Throttle Position Sensor – The throttle position sensor is typically located on the gas pedal.
