My EG6 started to hunt on idle but not that badly. I replaced the O2 sensor and cleaned out the throttle body and it made it a little better but its still there.


About to clean out the idle control valve but anything other to look at ?

Just cleaned out the IACV and its still hunting.

What else can i do and also how do i do the check light thing to see if there is any faults ?

 

Check for vacuum leaks.

 

will do thanks, but where is a likely place to check? Whats the best place to start?

 

Pull one line at a time from your intake manifold.
Then cover the hole (on the intake manifold) with your finger. If it stops hunting you found your leaky line.

Also make sure that the plate in your throttle body is mating up good.

Another thing that could leak is the seals around your injectors.

 

get a can of carb cleaner and spray it everywhere, if the engine starts to sounds funny when you are spraying the carb cleaner, there you found a vacuum leak

also check to make sure you get all the bubbles out the coolant
