i have an e30 320i. it doesent seem to matter if the car is hot or cold but when you want to pull away from idle it hesitates and splutters. once on the go its fine untill you hit the motorway, at around 79mph which is aprox 3900rpm the car starts to cough and splutter if you try and keep it at that speed, a bit more or less throttle and it goes away, any help would be great as i dont want it breaking down on me so i havent been driving it
