my 996 C4 cab has an uneven tickover when warm/hot. Almost to extent of cutting out. It has been suggested that an "Idler Valve" is responsible. Has anyone experienced same problem and if so how was it solved.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Could be a lot of things... bad gas (petrol), loose vacuum line, fuel pressure, fuel filter, etc., etc. I'm a little surpised that your check engine light hasn't come on... it usually doesn't take much to trigger the light. Your dealer should be able to hookup his PST2 tester and get a readout of "out-of-spec" sensors. From this they should be able to fix the problem.
