whats up..here is my problem..i have an Evo 8 2003 edition...my problem is ,intermittently during normal driving conditions.. when the turbo starts spooling up..the car starts to shake very harshly..more than a misfire..anyone have any clues to this situation..help will be much appreciated thanks

 

do you have an aftermarket BOV? how about and intake? sounds like a vented BOV leaking a little under small boost it will run fine if its floored correct?

 

Kinda sounds like an ignition problem, see if the plugs or wires need changing? I'm not even sure if the EVO's have plugwires (don't they have COP?) but if they do those could be gettin' bad. Also check to see if your MAS is connected properly or your vehicle is pulling any codes?
