Right...with my new friend REV on my iPhone I set to dicover the error codes causing my throttle problem (none!)

Oh heck!

p0641 - Sensor Ref Voltage 'A' Circuit open
p0122 - Throttle Position Sensor Switch 'A' Circuit Low
p0223 - Throttle Position Sensor Switch 'B' Circuit High input

This sounds NASTY

This is the very first time I have attempted to start this engine

Any help on what to do, would be very much appreciated!

Could be a dodgy battery......

Failing that there are two throttle position sensors, one attached to the top of the accelerator pedal the other is attached to the throttle body.

As one moves the other moves, one increases, one decreases (can't remember which does which) but they both have parameters which determine open and closed positions and these parameters are stored in the ECU.

I would suggest that a tired battery is your most likely problem as to get multiple issues with different components at the same time is unlikely.
