2004 Dodge Neon 4 cyl Two Wheel Drive Automatic 63000 miles
i have a dodge neon and when your at a idle it runs rough and drops rpms when air or heat on and even lights it pulsates goes up and down. Everything works good when driving but at a stand still runs rough and everything pulsates on car? No check enging on at all had battrie checked and alternater and cleand fuel intake? Still bad. Put it on a machine and no codes come up? Let me know what you think it is?
