MK3 flat spot

I've got a bit of a problem with my mates MK3, I believe it's a 2l 8v.
It's been running fine but has just developed a major flat spot between
2500 and 3500 rpm. Would any one have any suggestions as to what to look for
as I don't really know.

Cheers

Stuart

Try cleaning out the throttle body

Cheers I'll have a look at that mate, someone on VZI also suggested the replacing the temp sender as this can cause issues, any idea if this is the case? I'm trying to get a list of possibles so I can have a crack at all of them this weekend as he needs it running by tuesday when he starts a new job.

Does it hesitate or just not as quick ?

to be honest I've not driven it. He's described it to me as a flat spot, but I'll give him a ring and ask the question.

fool hardy, drop Guy a pm on here he has probably heard of this before.
