What year of Cruze do you have? 1.4 turbo I assume? ThanksI've searched the forum and saw a few threads about this(all old) and have thus decided that i'm going to start using some premium gas and when my engine cools down i'm going to check my plug gaps. Outside of this, and a pricey tune, what else can I do to get this Cruze to run right in this weather? it's currently only 94F(34.4C) and it's been running pretty sloppy today, and in 2 weeks I have to drive all the way from the gulf coast to Illinois, Any other low cost suggestions(and preferably not warranty voiding) would be greatly appreciated.
