Had the car only a few weeks now just back from a long drive and just before I got home my car felt like I had a puncture so I stopped had a look and there was no puncture but a kind of burning smell check oil coolant everything I could thing off ( not mechanically minded just to let uses all no I don't have a clue) anyway I drove it next minute the engine management light is on and when the car is driving it sounds like a helicopter there's a lot of vibration it feels like your trying to go up a hill in fifth gear and it's about to stall I agave no idea the engine management light comes on then flashes when I don't accelerate does anybody have any idea what this could be this is my first car just want to know what's wrong with it
