erratic idle between 1500 and 3000 rpm!

Cars been running like a dream over the last week.

However just started it and the idle is all bouncing around between 1500 and 3000 rpm

just had a cat back system fitted and its been running fine. Not sure this is related, car drives ok at speed but in 1st 2nd gears its hard to control....and noisy

Had a similar fault on a punto gt which was a vac leak near the ecu. Looked briefly under the bonnet but didnt see anything obvious, any common areas to check as im new to tsparks

Yeah. many common areas to check.
Air leaks in the induction system (air intake) and the fact you have just had exhaust work done, I would check for leaks in that.
Have a search around this forum for idle problems, you will find PLENTY of hits, most are worth checking, If you still draw a blank then post back your finding, good luck. At least you will get the know the car well during your search.
Here are some of my recent exploits:
