Only my 850 there was a tiny hose deep in the bowels of the engine that had split. Its about 4 inches long and 5-6mm o/d.

It might not be there on the newer engines but an exploded diagram would be a help if theres no obvious air leak. I agree you can usually hear them.

Still worth a clean - only needs a small amount of crud around the valve "hinges" to give that sticky jerky valve motion that causes the idle problem. Take it off, lay it on some paper towels or rags and squirt it through with carb cleaner - focus on the hinge regions and use a small brush to help get any gunge out.

ok ill try that john ill have pick up a new gasket for it when i get chance, ill also have a look for a split where you said edge

Right I have changed the pcv valve and cleaned the ecm (which was pretty clean) car ran great at first but after 30 mins or so and coup0le of stops started being funny again it did some hunting up and down,
it also did some revving to 2k without my foot on throttle then while driving it had no power and hardly went above 1500 revs but would go up to 30

also while it was sat at 1000 revs engine was rumbling like hell

after it was parked for 20 min was fine again think I need get it code read

I don't get the emission service check that's coming up walong with system service check

well got it connected to a vida/dice thing today and its come up with intermittent fault on throttle position sensor so hopefully just a break in wire or a dirty connection though it was fine today

Fingers crossed

That sensor probably isn't expensive - is it a variable resistor or a twin microswitch? probably the former i'd have thought.

Trottle position sensor is part of the ETM

A little snippet from VIDA attached
