My car is a 2003 Mustang V6 (Pony Package) with 120,000 miles on it. We bought it new. It runs OK when you first start it. About a minute later it will start to idle rougher Sometimes it even stalls. As you drive away it will run good and then suddenly chug chug and then good a again. This weird chug chug will happen until it warms up and then the car runs good. As long as it stays warm it runs good. Go in a store and come out, chug chug until it warms up.
It doesn't throw any codes. I even brought it to a local garage and he put it on his equipment (all I have is a code reader), no codes. After this problem started I have changed the plugs, plug wires, power steering pump, water pump, and idler pully. This has me stumped...seems like I am just over looking something.
