Slow acceleration when warm engine

[lambie]

Hi, my car is a Corsa Club T reg. Can anyone help with a problem. When the engine is warm and Im driving the acceleration dies and then picks up after a few seconds. This seems to happen more when doing over 3000 revs. The coil pack & spark plugs have been change. Any advice will be appreciated. Thanks, Mark

yea, my XE does the same in the cav...above 4k, it studders as it climbs the revs. it only does it now and again.

i was putting it down to the cat bein f**k and causin excess back pressure...but its more than likely a sensor. My guess is crank or poss AFM...but theres no way of telling!
