Recently ive been noticing when i try to pull away or up to speed in any gear, usualy 1st second and 3rd, the bottom end of the revs the car just struggles, judders and just wont give any power, once past 3k revs its all fine and dandy, but it seems to be getting worse, any ideas what this could be cheers

for what its worth I would definitaly whip the crank sensor out and replace it, check the timing would be a good idea ,if the exact rotation is out itll throw the crank sensor and the ecu will be telling the spark plugs to fire at ever so slightly the wrong time,this will cause the ecu to change the timing under different conditions if petrol is too low and cause predetonation. Just a thought from experience but im not 100% sure why its running good at top revs...hmmm. hope this helps anyway
