went to take the sx/4 to moparfest and it drove fine there only stalled once, but then after sitting in the show all day, it wouldnt idle at stop signs all the way how, any ideas what would cause it to change so abruptly?
It could be a rotten vacuum line fell off (causing a vacuum leak), or your idle tubes are clogged.
i put fuel in it before i left home, and also put in carb cleaner in the tank, and the hood and car were locked the whole time..
Check your PCV vacuum routing for leaks and bad line. This is a HGE manifold leak if so and will cause these issues.
