Cold Start Sputter &Techron did what?

[Paul_Royal@idx.com]

Hi Folks,

     Nothing major, but a couple of things are buggin' me today.

     For about a month now, I have to wait about 30-40 seconds or so to
take off from a cold start or the 90Q20v
     coughs and sputters a bit.  If I wait 30-40 seconds or just get it
going thru the sputters, it's fine..and continues
     fine until the next cold start...any ideas?  I used to be able to
drive immediately.  Car has a young 140K miles.

     Second...I'm leaking oil directly out of my filler cap...not much but
messy.  I recently used Techron in my gas
     and am wondering (perhaps stupidly) if this has anything to do with it
as I've heard the Techron does odd
     things to your oil as it slips by.....here's the kicker...my mileage
improved by about 4-5 percent...for the first time
     in my cars' one year 47 thousand mile history with me.  No matter what
I did I would end every normal work week
     with a computer calculated 23.1 mpg...I changed tires and it dropped
to 22.5 consistantly...put in the Techron
     and I'm at 23.5.

     Any words of wisdom?

     TIA..Royal
