Hi folks, just been speaking to somone whoes recently purchased a td5 90. When he turns it on it starts first time with no smoke, but has an erratic, lumpy idle. He's had 110mph out of it easily and it's very quick off the mark and rapid acceleration. No egr blank, large exhaust or uprated intercooler. Also (not sure wether it's connected) he said that when he has around half a tank of fuel it is runs rough (I think he said it stalled but can't remember:doh any ideas?
