Nice looking! Did you adjust the IAC valve. If you did, time to check for a vacuum hose leak.

Hopefully you did not remove slack from the throttle cables.

Yea I did adjust the IAC valve, But Whats Up With The smoke?

I would suspect a bunged O ring on an injector.

When was the valve cover job done?

[CroQ45]

The valve cover job was done 3 months ago!I forgot to add that!

[CroQ45]

If it is a bunged O ring, How can i tell?How can i find out witch one?

[Q45tech]

Use a Consult to adjust IAC and read the IAC solenoid duty cycle.

Are you sure it has been turned in fully then out 2.5 turns?
