Had a new waterpump and cambelt about 2000 miles ago,so no probs there,just got to sort a prob out with secondry air thingy or something cant remember what it was,the bloke who hooked it up and had a look said it wasnt a problem but i want it 100% before its mapped.i did a n249 bypass and got a apr racing diverter on it,and the problem didnt come up until at least a couple of months after doin that
