Thanks velocity, that clears up a few things, looks like the documentation I have I relates to a 3 door which explains why things aren't reading right.

When I checked the TPS (inside) yesterday, there was no way that the measurements I got in the documentation could be given by the TPS, hence my question on the difference between 4x4 and 2wd.

I will check the voltages tonight on the ECU and made triple sure the TPS it setup ok, then take it from there.

When I plug the ISCV back in, the RPM doesn't drop at all, stays there... That could be down to the TPS not being quite right though.
