As above!

After being fitted my lamdalink seems to be causing the CEL to illuminate. Any one have any experence with this??

 

Only thing that can be said is that you must have made a mistake fitting it somewhere. Have you checked the CEL code? One presumes it'll be the Lambda sensor, but it's better to know than presume/assume/guess.

 

Hope so, it was fitted same time as, knocklink, centre section de-cat+down pipe. It wasn't on before but came up soon as these were fitted. It also has recently had 30k service.

whats the phrase.... assumptions are the mother of all F***ups!!
