just trying to diagnose a problem with my car... not sure if its a dud sensor somewhere. but its a vx ss, it has an irregular problem, maybe once every 2 weeks when I go to start it whether its hot or cold it will turn over act like its about to run and stall straight away. might do it 3 times then it will start and run normally, then wont happen for another 2 weeks or so, plus it is idleling a lil rough. I am also using more fuel since I fitted bosch platinum/iridium plugs and new leads.
