Engine idling rough VY S2 Commodore

[Black-ice]

Hi all. First post on here. Thanks for reading. I have recently purchased my new commodore and have noticed that when its idling or stoped at lights, the engine is running a little rough like its missing. Its done a touch over 200k. I have recently serviced it changing oil, spark plugs and filters. Does anyone know where I could start to look for this problem. When its driving, it runs sweet. Thanks

Hello and welcome aboard.. Have you cleaned the throttle body? That could help or might be the tpc

 

[SID888]

Have you changed the leads?

 

[Black-ice]

No to both above. Ill try the cleaning throttle body before changing leads. What are the chances of the injectors needing cleaning?

Do you run the car low? Could try injector cleaner next time you fill up..

I have a vy commodore 2002 it has done alot of ks.
On idel it feels like it going to stall but it does not.
It idels around 700.
I have changed leads,plugs,dfi,coils
I have run out of ideas.
The only other thing i could think of is the air flow sensors that sit on the side of the throttel body.
Any ideas would be greatly appreciated.

Yes or could be a hole in a vacuum hose.

See the hoses coming off the throttle body id replace all of them just take one off at a time take into shop say u wanna new one

Then get tb cleaner and clean out your tb and spray all the gunk off the idle air controller, 2 screws on the back pops out, or get a new one

Else check your battery leads are neat and clean and tight

Tighten up all screws on air intake so no air leaks. Ecotec loves air so if u get it all sealed up she purrs
