10, Reiz ran to 60-80, and the rear row of the car shook, the cold car did not shake, and the hot car shook.

The front wheel alignment angle is inaccurate, the toe-in is too large, the front air pressure is too low or the tire repair is unbalanced, the front spokes are deformed or the number of tire bolts is not equal, the transmission system parts are loosely installed, the transmission shaft is bent, the movement is unbalanced, and the front axle is deformed.

Headlights and air conditioners need more fuel injection. When the air conditioning jitter is serious and obvious, the problem of mixed gas should be considered. Most of the problems are not the accelerator. If the electronic throttle is basically 10W, it is enough to clean it once, because the electronic throttle itself has self-adjusting function. Even if it is dirty, the opening will be adjusted to meet the air intake. The oil circuit is dirty, and when the mixture is not up to standard, it burns badly, resulting in jitter. The air conditioner needs more fuel injection, and the jitter is more obvious.
