Alright guys I can't finally post this up since I have even posts lol. Well heres the deal, I recently bought an 04 xB 1st gen and I just did an oil change because it needed one and changed the air filter since it was real dirty. When I'm driving and I put the car in D and drive away the car is perfectly fine and normal but when i stop at a light and I have my foot on the break my car starts to shake and I can feel it throughout the car but not through the steering wheel. This only happens when I get stopped at a light.Can anyone help me out and tell me whats the problem?? My dad said it could be the timing belt or like the idle??
