hi i have a sri vectra only a baby. i bought itcheap with the engine light on. the seller had it on the tech 2 and it came back cam sensor. so i replaced that with a new one and crank sensor just in case. but it still has the same trouble .... wont rev above 4500 really holding back and the plugs were jet black with carbon. since i have had it its ran fine once.... any ideas
