Engine shaking at idle.

[Slipstreem]

Wow that's really strange. As I was reading this I was thinking injectors until the compression test. At 50k miles it's not even broken in so I highly doubt rings. Does it smoke at all from the exhaust?

It is odd. The car pulls fine, given how well it accelerates and the lumpy idle to begin with I though tricked cams till I lifted the cam cover off today. No smoke from the exhaust, etc. I have a spare coil pack and inlet manifold complete with throttle body, injector and idle control valve. I'm tempted to swop over all of this.

what I found strange yesterday was turning the idle screw did nothing to the revs. Also if I unplugged the idle control connector for the ecu or the throttle position sensor for the ecu the revs would increase and the engine shaking would go away.
