So sometimes when I turn on my 08 GSR I get a lot of vibration on file it only seems to be inside the car and if I apply pressure to the wheel it lessons , and when it's running it goes away almost completely , any ideas??

 

'Pressure to the wheel' - does that mean turning slightly and loading the power steering?

Vibrations only at moment of start up or cold idle?

 

I mean like pressing down on it , and it's not the whole car itself only Inside , cold idle , if I begin to rev the engine it goes away
