I have a 2006 SR Hilux V6 4lt petrol ute and when I take of from stand still (especially on a hill), it will stall or jump unless I ride the clutch and/or put the revs up. Sometimes its ok but most of the time its not. When I'm towing a trailer it is much worse. It seems to have no power, then when u r about to change to second it comes good but it will do it again in second gear. I can smell the clutch burning a lot of the time but there's nothing I can do for it will stall if I don't ride the clutch. Is this common? Can it be fixed?
