Hi guys and thanks.....may have an issue to solve, my local garage checked the car over and the only 2 things they could see that might be a problem was tracking and emissions .....now the tracking I am going to sort out tomorrow, but does anyone know how to get the emissions down ....my CO is around 4.5 and needs to be under 3.5 ....I have heard retarding the timing a little helps.
no cat or lambda, never was any.
Trailer works brilliant by the way
