morning gents, my td5 100 when started from cold wont rev for the first 15 or so seconds, i have tried holding the pedal and pumping the pedal, still nothing even when it finally revs for another 15 seconds its low on power so much so that it stall when going over a mole hill but after that its fine, pulls like a train but then every now and then when its hot it has the same issue, last night i was driving it for 45 minutes, pulled up at some lights, whent to move off and nothing, just died, also put out a fair amount of white smoke, im guessing its using coolant and so has a chack in the head? would this case the dead revs issue?
