Help needed guys

[Debby]

Please can any one help me?
I have a Bravo SX80 and i keeps pulling back at about 1500rpm its fine at all offer revs.
But not all the time, its when i switch off the engine and start it again. But again not all the time.
So when i take it to be looked at guess what the thing doesn't play up!
I have change the spark plugs and HT leads.
Any idea's..

what do you mean by pulling back? revs drop or what happens?

 

[Debby]

Its sort of like a misfire, just pulls back and judders always at the same point when its playing up.

Could be a plug, lead. injector,

I have changed the leads and spark plugs, had the car for about 4 years now and its always done it.
But it seems to be getting worse.
I was wondering if it could be the idle control valve as the revs do rise and fall at idle when it is play up
But don't know where it is or what it looks like though.

could be the MAP sensor, It is on the inlet manifold at the right handside

Could be a dodgey rev limiter??
