I have a 2005 dodge stratus sxt coupe. The idle runs rough when im stoppes at a stop sign or a light and I have to kick it in neutral for it to calm down. I changed plugs and wires and have a used transmission with 70k miles on it put in it last winter. I need some input on how to fix it. Im thinking the fuel filter but not sure I wanna go thru that trouble if its not the case.
