High voltage reported on another post (idle speed valve) turned out to be a duff alternator - but those two (IIRC) run off an ECU generated voltage...

I suspected the TPS to be suspect with my first problem of the idle going up and down from 1000 to 1500 RPM when car was warmed up.

Have you read the battery voltage with the engine running?

To add - I've never seen a V6 TPS fail.

Usually the codes are caused by an underlying electrical problem (often the regulator)

Stick a multemeter on the battey at tickover, and vacc test it - and let us know the findings.

I still suspect an air leak is contributing.

Had another try to get Omega going today.

Checked all the Vac pipes and all ok.

I could only get the car to run when I removed the Ram pipes from the Inlet manifold.

Also would only idle if pipe from ICV was removed from ram pipe.

Any ideas?

Blocked or too dirty air filter?

Faulty air flow meter?

Well when i did clip test faults came up on TPS high voltage and  Mass Air flow sensor High voltage.

Could it be that then?

Before these probs the idle when warm was irratic going from 1000rpm up to 1600 RPM and back constantly.

The TPS connector is easy to leave off when doing work and without it the car runs pretty poorly. I'd get that error cleared then see where you are. Could be connector or wiring damaged somewhere.
