hi guys this is my first post, i have just got my first bmw and i love it! but there is a few problems......:confused where do i start ..... well it smokes alot when first started and is very very lumpy as if its not firing on all cylinders. if you put your foot down it smells of burning plastic and smokes white with a tint of blue ....? also it lacks power alot after the car being stood for a few months after the previous owner fitted a flame kit that blew the ECU i think that half the problem could be that it has not had a good run and may need the injectors cleaning out and a full service. i have a suspition that it is the head gasket but i just wanted some oppinions on the problems. can anyone help? thanks jay
