Please help--car shakes
 

I have had a problem for some time with my SVX where the car shakes pretty bad when driving, and it is way down on power. When chasing this problem earlier, I discovered that my crank pulley was bad, so I fixed that problem. But the car still shakes and is down on power. I checked the timing, and that is okay. Does anyone have other ideas? I really need to fix the car, as it does not drive very fast now until it warms up, and even at that it vibrates. I would really appreciate any help or suggestions. Thanks!

Do you get any engine codes?

Perhaps you have a bad coil. We need a lot of information to help diagnose the issue.

Check if the spark plug wires are on correctly.

where in NC are you?


and check your wheels too

Could be wheel aligment maybe too...

Sounds like a problem i had recently. Turned out to be a dead coil.
There is a way you can test them easily.

With the car running, unplug the fuel injectors one at a time. The engine will obviously run differently when you unplug one. but if you unplug one, and the engine doesnt change, you know that is the cylinder that is not firing. So check the plug first, and if it looks ok, it is most likely the coil. I think they are $85 at subaruparts.com.
