Suggested SolutionI had a similar prob. on my Tigra mk1, [1400 cc]; the engine was over-revving [2500 rpm] at idle; I found the prob.to be a trapped tube which I caused when re-placing the upper manifold, after removing & cleaning the EGR valve-the small=bore plastic tube goes to the MAF sensor; repairing & replacing the damaged tube rectified the over-revving & "hunting" problem.
