Whilst driving today my car lost a bit of power then came back it done this a couple of times then i noticed the revs kept dipping, but once i got to work it was fine,then on the way home it done the same thing. I popped into the garage i go to and he said the throttle block needed to come off and needed cleaning as a flap was not opening or shutting properly and said this is what is making the revs dip.      I want to know if this is right or if anyone has any other ideas i need to get this done as quick as i can as i am going to somerset on holiday this saturday with the family and dont want to let my sons down. PLEASE HELP

Right track

1) Make sure throttle body is clean, both sides and especially the edges of the butterfly

2) Make sure the breather from the camcover to manifold is clear, if the hole is blocked in the manifold breather drill it to 1.5mm!

3) Ensure the crankcase breather pipe on the passenger side rear of the block is cleaned out.

4) Clean and lube the ICV.

Any fault codes?

check your throttle body is nice and clean first and foremost.  If not, give it a good clean, detail on how to are in the how to section and are very concise, I did it!   Oh, check all your breathers too and it might be worth cleaning your icv if the throttle body is very dirty!
It could also be a sensor breaking down, I had a similar problem which turned out to be the temperature sensor in the block for the ecu, cheap to do but awkward to get at.
Hope this is useful?

No fault codes i might sound like a wally but do the older miggys come up with fault codes any way no is the answer.I am putting it into the garage tomorrow as i have not got a clue but i will write down what you have said and pass it on as i dont think they will do all you have said. Thanks for the advice

All advice is good, thanks for your help

No fault codes is a good thing in most cases, unless the bulb is either blown or 'missing'!
Yes, older miggys do give fault codes and are easy enough to read without the 'help' of a garage.

Since you have no engine management light on, should just be what James and myself said, needs a good clean up!  

(yes, I realise what I've just done and yes sir, I'm an idiot!  )

The engine management light did come on for about 2 secs and went off again the garage said this was just where the revs dipped so low and it has not come on again
