I've also been having issues with my lambda light, it has come on twice now both times showing the same 1-2-1 fault. Each time the car spluttered a little for about 10 seconds as if there was a fuelling issue (dirt in the injectors maybe). First time I took it into my local garage as I needed the exhaust changing anyway and I thought that this was probably not helping. The mechanic found nothing wrong so reset the light and all was well until it happened again.

The second time I went after the fault myself and using the Haynes manual and a multimeter checked all the MAF readings, and sure enough the resistance was spot on and the little voltage surge occured just as I turned the engine off. The car drives fine and if anything my mpg seems slightly better so I am currently ignoring the light.

Just one question - how do you reset the light, I have followed the procedure in the manual and the light stays on, or does this mean that there is some other fault?

My car is a 1992 SE with a B230F engine

Thanks
