Corsa 1.2 12v club - emily2
I've had my corsa for 5 years now and just last week I noticed it struggling to set off in first gear, it was as though there was no power, I would put my foot down but it wouldn't go anywhere especially when the engine was warm. The engine management light came on when it was struggling to get up a hill in 3rd gear. My local garage read the code which indicated a problem with the oxygen sensor, this was replaced and was ok for 4 days and then the engine light came on again this morning. Any ideas what the problem could be?
