Chevrolet optra 2005 model - engine is shaking starting from 70 kms/hr, strongest at 80kms/hr. Diminishes once you step on the gas. Had wheel alignment, changed tires and balanced, but still the problem is there. Does it have something to do with the timing belt, this has not been changed. Changed wires and spark plugs.
