Scion Xa Engine Shaking
The most frequent causes of a vehicle shaking while driving stem from tire issues.
Scion xa engine shaking. Tire replacement realignment and rebalancing are common solutions. When the air conditioner is on it put more of a load on the engine causing the hood to vibrate more. My scion xa is shaking when idle help please 2005 scion xa it might just be that the air filter holder is somehow knocking on a 015 012part of the engine. This has been mentioned on other forums and the fix is to put more pressure on the hood by raising the rubber stoppers.
When i turned the holder away from the engine and 015 012then retightened the strap that holds the filter housing properly i 015 012lose the knocking. Tires begin to behave differently when worn or out of balance. An engine misfire is the most common cause of a shaking idle and as the engine stumbles and misfires that should be seen in the tachometer as a drop in rpm. If the tachometer is rock steady and the shaking seems worse in gear than out of gear that s a pretty good indication of a bad motor mount.
