hello
i have just replaced cam and crank sensors and carried out a full service on my 2 litre omega,in normal use it drives a whole lot smoother and is a lot more responsive than it has ever been.
one thing ive noticed is the idle speed,it is idling at around 1100 rpm when you come to say a junction,or you come to pull up.
the idle gradually drops to around 800 rpm,but occasionally stalls,but fires back up immediately without a problem.
ive had a quick look at vacumes and the like and the only thing i can see,is that the big breather hose on the throttle body side of the engine,feels soft,squashy and can be stretched like clay.
is this likely to be contributing to the running issue ?
thanks :y

Have you cleaned out the breathers and throttle body?
-
to be honest no.
that i guess is my next step.
as i say,the large breather isnt great,you can press it together by hand and it dosent return to shape.
i may replace this,check the others and give the throttle body a clean up,if thats whats needed.

Take the idle control valve off too and give that a good clean out. Common problem on the 2.0ltr veccy's so would suspect its the same on the omega. They get all gunked up and stop working correctly. its on the side of the throttle body and looks like a long cylinder with a diamond shaped 2 bolt fitting onto the throttle body.

There's your probable solution :y
