Help had the car MOT'd and passed witrh flying colours. Driving car out of garage, it would start perfectly and then lose all power at 3k revs. I have put it in to the lexus service department and they have had it hooked up to the diagnostic machine for 3 hours and still cant rectify the problem as no faults being reported. Reading other posts, could it be coil packs? Any advice welcome before i spend any more on getting them to find out the problem Thanks
