Hey there I know nothing about the tds but I've had a shitty lumpy idle for a long time now and I rencently inspected the HT (ignition) leads only to find a broken sensor (you probably saw my thread)... Turned out to be something called a pulse generator and I fitted the nw one today. The idle is 1000x better and it feels like a new car! Just incase you have the same prob without knowing it bacause its such a cheap and 'easy' fix... I'm going to post a thread on it I think.
