How are the plugs and wires? mine shook like you wouldn't believe till i changed plugs and wires. It was more of a vibration though? Is it a vibration or a shake?

It could the Mass air flow sensor. My friend had that problem except it was randomly at any rpm. So he took it to advance auto and they hooked up a scanner to it and they said it is the mafs. So you could go to advance and have them scan it to see whats wrong with it.

[Ced]

It's a stock gauge the car is pretty stock just got it. But the previous owner removed the BCS (boost control solenoid).

Does it shake when it you hit 4500 in any gear or is it in one gear? It almost sounds like bad spark plugs and wires, i still think it could be that. My car would drive just fine till it went full throttle and then it would shake like crazy. I need to know if it does it in every gear, also does it do it when its sitting in neutral?
