Hi All,



As you know I just got a used C8 year 2003. 


Several errors just popped up with the anti pollution error, From the scanner it says:-



Throttle/Pedal Position Sensor/Switch A Circuit Range/Performance Problem



Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1 (Rear Bank)



Heated Oxygen Sensor (HO2S) insufficient switching bank 2 sensor 1 (Front Bank)


Yesterday night it was perfectly fine, no errors, then parked the car at the supermarket, came back and the car couldn't start, kept saying immobiliser fault. And then after a while of waiting around it managed to start, somehow the immobiliser fault dissapeared but the rev was completely crazy it went up and down as if it was going to die out


and then it dies out, 2nd try again, i rev the car high up and let it go it drops straight and dies. 


Third try again restart, rev goes up and then drops and dies


Fourth try, it manages to hold but was wobbly, then i immediately drove back home, it kept dying as i was about to slow down or stop but luckily i kept flipping the auto gear to neutral and press on the throttle so it doesnt die out. Reached home and as i parked the car died again but thank goodness we reached home.  


Those error codes are the only ones showing. Any ideas, I called one citroen specialist and he tried to rip me off by saying that the engine is choking and there's carbon build up around the heads and i would have to remove all of it and replace it with a custom made one, which will cost me 4 grand, so i told him my kidneys don't cost that much. 


Any of you guys know about this issues? My mileage is at 114000kms at the moment and have no idea what has the previous owner done with the servicing and etc. 


I've got a leak on the coolant pipe underneath the engine not sure if its related or not. 


greatful if u guys can give me some help here. thanks!
