So, lately when I get into my S in the morning, it seems like it has a hard time starting after just sitting overnight. Today I got in it and started it, and it sat there on its own barely running for two seconds or so and then revved to life. I have a brand new K&N on there so you can rule that out. Just did an oil change and put in Valvoline synthetic 10W-30. Checked spark plugs today and re-torqued them. Obvious stuff aside, what do you guys think this could be?

i wouldnt worry about it. it happens to mine all the time when its really humid out. on some morning when i start her up it bogs down and sounds likes its going to die but it doesnt then it goes up to normal.

I have similar problems when its colder than 0 degrees... its retarded.

was there recent climate change? your ecu still maybe learning... mine does this if my car was in the rain and i let it sit. if i come back to it, it will start but feel like its going to die, i let it warm up and she's ready to roll

Are you guys on stock ems?

I hear about this stuff with AEM EMS with guys that didn't have the cold start issue tuned enough but stock it should fire up right away every time.

the car is sensitive to drastic climate changes.
