Advice Please

I have 316tise, 2003, 12000 miles... Have a flat spot when excelerating in 1st and 2nd gear. only does it now and then but is quite noticeable when it occurs, only at low revs and only
happens for a few seconds - then car accelerates as normal. Also when engine is cold, when pulling away in first gear, the engine faulters and is strugling to rev, then it is ok, its like there isnt enough choke when cold......
thanks you
