Hi I have a 2008 Vauxhall astra 1.9 cdti 120 and when I accelerate to about 2000 revs it feels like its holding back then if I put foot down a bit more it will go there is no smoke at this point and also in top gear when driving say at 1500 revs the car seems to jump abit then clears , wondered if the first problem could be egr valve or boost control valve but do not know what second problem could be thanks
