You may have to get your wheels re balanced, or you may have a tire gone bad. Check your tire pressure and have all the wheels balanced at a tire store.
The other thing you could have is worn front end parts, like ball joint, shock bushing or shocks. Try greasing all the steering linkage and see if the vibration goes away, which would indicate worn steering parts.
Start with the tire pressure and then grease all the front end parts, if the vibration still there. Then have the wheel balanced and check for wheel alignments.
Good luck and hope this helps

Check the fluid in the radiator and not in the reservoir. IT should be full. It should be 50/50 mix with antifreeze and water. Check the thermostat to see if it is sticking, Check the water pump for excessive wear on the impellers.

sounds like the fuel pump is not putting enough fuel through to keep up with the demand of 110 km ph
but is putting out enough for the 80-90- km ph
