Only happened the other day.. engine would start then cut out once the accelerator pedal was pushed, the three codes appeared on diagnostics 12,22,42, which I have then checked the ignition HT leads dizzy etc, I cleaned out the dizzy, saw no cracks on it, the rotor arm looked okay also (might be worth replacing them do you think?) WIll be checking all my earths tonight when I get home, the coolant temp sensor is all plumbed in fine so no idea why this is flagging up? maybe new coolant temp sense required? any advice on where to go next?
