I've had the MAF changed in november last year & while my car can go over 60mph & 3k revs now its still running uneconomical. The guy at the MOT had to rev the engine alot to pass the MOT. I noticed myself that the cars drinking alot of petrol as I'm a granny driver now (since I crashed my FTO on the motorway)

I had an auto-electrician look at it & he first said its the CAT. then he looker further into it and said its the LAMBDA sensor. He had a smartbox he used and this is what it came up with.

Total codes: 001
CODE001:
P0130 G3/4 (02-CAT front right)
----------------------------------
I've spent alot of money trying to sort this car out. 1st the MAF then this. Can anyone confirm if its really the LAMBDA sensor I need to replaced.

If the Lambda is faulty it can go either way, a too lean, or too rich. It does control the fuel ratio
