    E46 316 TI compact 53 REG, MIS FIRING WHEN STARTING THEN CLEARS AFTER 3 MIN DRIVING?

    hiya all ive recentley bought a 53 reg 316 ti compact, i gave it a full service straight away.one of my problems was a lumpy idle.so i bought some injector cleaner.so i poured it in filled my tank to the brim and set off on a 300 mile round trip to newcastle.
    the car fired up like normal and i pulled away only to get around the corner for it to start mis firing and limping along.i continued with foot to the floor and putting my clutch and revving it hard, it cleared after a few minutes and off i went.the car ran perfectley and after two hours i stopped at the services for a brew and the same thing happened leaving the services, luckily i was at an off the motorway one and drove down an A road.
    it got me back home so this morning i fitted a new fuel filter thinking it had dragged some dirt through but its just the same any ideas would be much appreciated, on a brighter note it idles perfect now haha.

    Have you had the fault codes read from the engine ECU? If not then this would be one of my first ports of call.
    Any rattle noises from then engine? chain tensioners can go weak on these engines.

    I'm just looking for an old laptop on eBay see if I can get inpa running on it and plug it in .
    Bit of a coincidence that I put injector cleaner in a d now it won't run right?
