To my ear it still sounds like it's stressing, but like I said, not too experienced with cars/mechanical stuff.

First off I'm glad you figured out the "glitch" the car was having... the loose nuts behind the wheel... J/K.... and yes there are 2 different formulas of gas for different temp. ranges.... just like diesel you need to put an additive in it in the winter they add something else to regular fuel also which causes a drop in MPG (can't for the life of me remember what it is) it's a heavier mix in the colder regions and the gas actually smells different.. if I'm not mistaken when they started it it was called oxygenated gas but have since renamed it.... I notice a difference between Rhode island and nj gas consistently.. I drive back and forth all the time only 3 1/2 hours but always a 2-3 miles per gallon difference at least with better mpg from NJ gas no matter where I purchase the gas, or how I drive... Must be a new england thing to add more to the fuel then in NJ
