Background: '05 MCS with 68K on the clock, running on premium unleaded all the time (but do get 10% ethanol blend). Problem started back early on in the summer once the weather started to warm up.

First start in the morning is no issue - engine starts immediately!

Anytime past that takes several seconds of cranking to start.

Once running - no problem.

I have read a lot on Sea Foam treatments, MAS issues, etc...

With no warranty and no local dependable shop I'm pretty much on my own trying to diagnose and resolve - any thought or help would be appreciated!!
