ok guys guess what i changed my manifold because i thought it was faulty and the swirv bar kept falling off, anyway i changed it and drove it, the car will hold back, then i checked what i did and found i missed to put a eletric clip back on(engine light was on), now when i drive it .the limp mode kicks in(engine light is off but spanner comes up), i have cleaned the egr valve by taken it all apart also cleaned the booster sensor, what else can it be, how can i check if the egr valve is working ok??. any hoses which ones and were are they located, this is really bugging me now, i only had it 1 month and is very powerful but now dont like driving it, was thinking about calling the AA recovery when its in limp mode but will they be able to help
