I have a problem with my car shaking at idle with the gas engine running. I've noticed that this happens at a stop, with the foot on the brake. This happens at a stop light, in cold temperatures. The engine is running to provide heat in the car. When I have my foot on the brake, the car will shake at idle. But I've learned that if I lift my foot off the brake a bit, there is a point where it feels like something disengages, and the shaking stops. It's almost like something in the powertrain is trying to push the car forward when it shakes. I thought it was an engine misfire, but the dealership says no error codes. I also think the shut down of the engine is very rough at times, and will actually rock the car. It can also take about 5 seconds to shut the engine off, and the entire time it feels like the engine is misfiring, and visibly shakes the car. Again, no error codes, so Toyota says 'no problems here'. This doesn't seem right to me. Does anyone else have a rough idle like mine?
