Default Rough idle after start-up??? Does it about 5-10seconds after cold start.

Just started noticing this on cold startups. It does it after start up and sounds like it starts about the time the air pump starts running. Starts to stumble and almost stall and then the idle goes up and smoothes out and runs fine after.
Any ideas???

Typical. Wait 'till the big 'OK' before turning the key to start.

I wait till the fuel pump shuts off-thats the real ok. It still does it though.

Default Mine does this also, waiting for the 'OK' doesn't make a difference for me..

and I have a feeling it has to do with the shell v-power gasoline I put in it cause it didn't do this till I started filling up my tanks with that paticular fuel. I am confident switching to another brand will fix my issue.

Had the same problem, dealer cleaned the injectors and TB, and fixed a vacume leak. Was fine after.
