Possibly a faulty MAF. Could be a number of others though, could do with a bit more info.

hi paul the problem is that when vehicle is cold it is fine when it heats up in third gear it starts misfiring when you put the foot down. does it 4 and 5. someone has told me that it there is water in your fuel tank and thats why it is doing it. i have changed the air mass meter, serviced the car, changed oil filter, fuel filter still no luck.

You say it only does it when cold, well that would point to a temperture sensor problem. Thing is misfiring isn't usually the common fault if the temp sensor is KO'd. Sounds really strange.
