running rough

Hi there i just bought a 2003 bmw 318i 2.0l petrol 111,000mi , when i bought the car it was fine and was running well for about 3 hours, after that i went on to the motorway and i went true the gears and once i hit 140km in 5th gear at 4,000 rpm it wont not go past that in rpm(sound like it was...

Hi all, ive just bought my first bmw m3 convertible and i love it, but its running abit rough and it sometimes idles above 1000 rpm, however when i turn the car off and restart it its fine, when i take it for a drive and stop it starts idling high again... any ideas..??? also as its left...

any 316 e30 experts out there my 89 316 is running like a pig backfires coughs and splutters im sure its electrical because the rev counter is all over the place now and goes up to 2000 rpm as the ignition is switched on any ideas or anyone had similar prob? many thanks
