I have the above car. The problem is when I am accelerating the car starts to shake, its ok till I get to 50mph, but when I accelorate more it starts to shake, I thought it was wheel balancing, but had all 4 done and still the same...... Soon as I take my foot off the accelerator, no matter what speed i am going the shaking stops. I was thinking maybe its the fuel filter, but I am guessing. Any help would be appreciated.
