Do a compression test. Possibly a blown head gasket. I hope not.

Err I hope not too, although I did 40 miles before it does it

You drove it hot for 40 miles???

Sorry my mistake in my wording the car does not overheat or get hot , it just doesn't feel rough when I first turn it on

Well that's good news! Do you have a CEL light on the dashboard?

Yes

I shall get the computer on it today

Possibly a bad coil pack malfuctioning when the car hit normal operating temp or MAF sensor. The CEL code should reveal the exact problem.

I am thinking maf sensor
