Why does my car idle at 1100 RPM?
High engine idle can be caused by a number of different things. A stuck/binding throttle, vacuum leak, bad throttle position sensor, coolant or air flow sensor all can be the cause of a high idle speed. Have a certified technician perform a diagnosis for the high idle to find which is the cause.
Is it normal for a car to idle at 1000 RPM?
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. A cold-start rough idle, for example, may be caused for different reasons than a vehicle that idles rough only when the engine’s hot.
Is it normal for a PowerStroke van to idle rough?
My 97 7.3l powerstroke van has started to idle rough but only when warm. At cold start is sounds/feels normal. At any RPM other than idle it also sounds and feels normal. When idling warm it is very rough, periodic vibration that feels like it is stalling. It has not actually stalled, there is no smoke at warm idle.
Is it normal to have rough idle at Warm start?
At cold start is sounds/feels normal. At any RPM other than idle it also sounds and feels normal. When idling warm it is very rough, periodic vibration that feels like it is stalling. It has not actually stalled, there is no smoke at warm idle. Some smoke at acceleration from idle but none accelerating at higher rpms.
What causes the engine rpm to go up when idle?
When the engine idles, there will usually be a misfire that you can feel just from holding onto the steering wheel.

The RPM will usually go back to normal as you accelerate the vehicle, but will increase again after you stop.
What does warm idle feel like on a diesel truck?
