Problem when hot

[Bodders]

I have a marea weekend 1.6 and it has just started to play up when the engine get shot (after about 20 minutes of driving).

When it is hot, it judders when you try to accelerate. Take your foot of the gas and press it again and it is ok (sometimes have to do this 2/3 times). The rev's stay the same and it is as though the car is pushing back.

I have replaced the coil, plugs and leads, cleaned the air filter etc and it is still doing this.

When the car is cold there is no problem whatsoever.

Anyone got any ideas ??

What do you mean by hot? Overheating? In the red? Halfway etc. Is radiator fan coming on? Coolant levels ok?

Engine is at normal running temperature, sensor is in the middle, coolant levels all appear ok.
