I'd go with TPS too. Easy enough to check with a multimeter.

I cant remember if you have nano, but if you do then I think you should be able to turn on the ignition and then take the voltage of the TPS as you press the accelerator ie even with the engine stopped.

Low fuel pressure? One lambda sensor not working just means one bank will run open loop fuelling but it will still run fine.

Are you sure that you want to perform this action? This action is irreversible.
