I had this problem, after changing everything and it still doing it, it turned out to be the crank sensor.

It's all working now, fine and dandy :D

They replaced the throttle body, temp sensor, crank sensor, and something else (don't remember as the mother picked it up), reset the ECU etc and it worked lol

Thanks for the help guys :thumbup:
 
Oh but the petrol gauge isn't working now for some reason, is stuck to empty, and the tank is definitely full,.....

it wasn't like this before it broke down, is this just a problem with the clocks?
