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!
