Nice description of the problem.
FWIW, I and others here have had this problem and with the recent weather, it's back......
Some FI cleaner makes it go away (I think) for a week or two and then its back. 92 octane lessens it but not all the way.
If someone has actually cured this problem (short of Lance's intake teardown) please post!
Thanks,
