Nissan Note 2007 1.4 litre. - Lumpy power. - Millers57

I have recently purchased a Nissan Note 1.4 with 33k on clock.It ran perfectly for one week returning 48mpg.Out of blue engine felt a little lumpy with power tending to surge when pressing the throtte.Fault appeared to disappear as I was going to return it to the garage then later that night the fault returned & the engine management light came on,Does anyone have any ideas what the problem is before I call in at the garage as they may try to fob me off.

Your only alternative would be an auto electrician who may be able to read the fault codes for you but I would speak to the garage first.

Garage read fault codes & said it was the oxygen sensor that was at fault causing the engine to run rich.Parts ordered to be done Monday.
