Question about 2002 GMC Sierra

1 Answer

Upon reaching and holding 55mph using only the accelerator, my truck begins to shake and vibrate and move forward in a jerky fashion. The problem goes away if I coast or if I begin to acceslerate. What's going on?

Having an alignment done usually only corrects the car pulling to one side. Check the rear tires for balance and wear. You may also want to have them rotated to the front to see if the vibration also moves to the front.

What makes Audi A6 2.4 1999 to shake before it reaches 80km/h


Unbalenced wheels..Bad tiresBefore 80 is too slow it will shake and wave and vibrate.After it can stabilise or get worse.Last:bad motor sensors:air intake,valve timing etc. If not ruff acceleration (rpm related vibration) then is the wheels related (unbalanced,bad/defect tires,low air pressure,loose nuts...)A windy weather also shakes u well :)))Cheers.

Right front tire seems to wobble, shaking. Engine area of car shaking over 55. Mech friend says it's the rotor. Worried about driving.


A bad rotor would only cause a shake when you are using the brakes. A bad tire could shake at 55mph and above.
I would get a second opinion to make sure.
The shop could rotate the tires and see if the vibration moves to a different area of the car.

WHY DOES MY CAR VIBRATE AT 55MPH & FASTER?


If the vibration is in the steering wheel a tire out of balance or a separating tread could be the problem. Have it checked at a tire shop or move the front tires to the back to see if it goes away.

Jerky accelerating, late response to gas being pressed


Well for one, make sure you speed up slowly, dont HIT the accelerator. It may also be problems with your fuel filter. After you are stoped fuel stops running through the fuel pump/filter and then when you start going its starts to run through again and it cant keep up so it gets bubbles in it and doesnt move throught the filter easily hence the jerky accelerating. Good Luck
