| Ah hold on, seen this before on a sport, try disconnecting your front lambda sensor, if it goes away then its a faulty lambda. | |

| Its back... Replaced the front lambda sensor which kind of fixed the problem but i still have that miss fire, a few people have suggested that it could be the coolant temp sensor Driving back from finns tonight my engine light came on, got the fault code reader on it and its complaining about the lambda sensor bank 1 I had already changed it for a Bosch one could it be my coolant temp sensor which is bringing up this fault? | |

| Maybe just a dodgy sensor take it back mate if not new it could have been on its way out when you bought it thats the risk with used parts.
If new then your well within your right to a replacement mate | |

| Was it a new or second hand lambda you fitted?
Tried two s/h ones on mine last week and both were faulty (working when removed) so had to take the hit and get a new one. | |

| it was a new one, but could over fuelling caused by a dodgy coolant temp sensor cause it to fail? | |
