this Fu**in VL again

[cjwau]

guys,
have posted here before about this car and got very valuable help regarding my issues.
I was sitting in my car the other day doing some electrical work when all of a sudden the car cut out and wouldnt start again. checked the fuses first all good. still wouldnt start so i went through the motions, got spark - yes, got fuel - yes, changed the CAS seing as is so common still nothing. I tried the fault codes and all it came up with was ignition system and system ok code 23 and 31. checked what i could think of seemingly no issues. tried fault codes again and i came up with trottle system. Now my question other than what the **** is the problem is when it refers to the throttle system does that mean the throttle positioning sensor?? if so have not long ago replaced that to. I am going round i circles with this car and it's starting to get really annoying! If anyone has any ideas id be happy to hear them!

throttle position sensor can be cancelled simply by depressing pedal to floor and let it return to normal.
this will remove the code u have about this.
i would say u have shorted something somewhere.
what were you doing as such??
