    Alright so when my 323 warms up there's a serious lack of power low down and it splutters a bit, uptil about 3.5k and then it comes on again, if i pull away from a junction the car will just about move at around walking pace with my foot flat down. It's getting to the point where it's becoming a bit dangerous now.

    The MAFs good, coilpacks are good, spark plugs are good, lambda sensors are good. Plugged it into diagnostics and nothing comes up. Check for any vacuum leaks, Cats not blocked as I de-cat'd it. So i'm a bit stumped.

    Anyone got any suggestions as to what it could be, as if i don't get it sorted soon i'm just gonna bang a 328 lump in there as it's starting to ruin my enjoyment of the car.

    Cheers

    Had similar on my compact 328, ace when cold, dog slow when warm. Crank sensor was bad.

    Crank sensor... Or maybe coolant temp sensor.

    I must have read 1000 forum posts trying to find a similar problem... your description was the closest, so I bookmarked it and returned to it. Took a chance and bought the crank sensor and it solved my problems too!

    Huge thanks to guys!
