check light problem

[Jon]

Hi guys thanx for all your help with the missing bhp. It was a split pipe.

The next problem is that the car has a check light problem caused through the pre cat being removed by power sport when they removed it and replaced the other cats with 100 cell ones. Franklin have just brought my car back saying they could fix it by moving the lamda sensors to a different position but it would cost around 400 quid and they couldn't guarantee it would work.

any ideas as that yellow devil is doing my head in!
