MCSF light on constantly...help!
Hi peeps, I have a 2.0TS 147
A couple of months back my MCSF light came on, the car started to run quite lumpy on tick over and there was a flat spot at about 2500rpm. So I took it to a garage and they said that it was one of the lambda sensors. I changed it and the light went out for about a month and the car ran fine.
But since then it has come back on, it runs even worse on tick over, almost stalling then the revs rise again. There isn't a flat spot this time. My fuel consumption has gone through the roof! Normally I get around 28-31mpg but now im getting 22-23? I can smell really strong petrol fumes as well when im driving!
thanks in advance.
