I have a 2009 Dodge Grand Caravan with 134+K miles on it. In 2015 I was on here for months looking for a solution to a problem with my van stalling at stops. It had been to multiple dealerships/mechanics from April thru October of that year. After $2300 dollars a Subaru mechanic figured out that it was the wire harness which cost and additional $1K. I'm really worried because for the passed few months I've noticed that the idle has gotten very rough and sometimes it feels very much like it's going to stall.This is only happening at stops again. Last night the rpms dropped a little and it felt like it was going to stall. I'm terrified of this whole thing starting over again where they just keep throwing parts I can't afford at the car until they get it right. In 2015 they replaced....
-throttle body
-Map Sensor
-Cam and Crank Sensor
-EGR
-TIPM
-plugs and wires
-Ignition switch
-ECM tested and that came back fine

PLEASE HELP!
