dodge

#1

5.7 Ltr automatic with 100K miles. Engine light on, misfiring. Replaced plug and coil still doing same. Make a lot of noise when cold. Help?


#2

What codes is it setting? Specific numbers, i.e. P0302 or something in that format. And is that why you replaced one plug and coil? Why not all? Post back with some more details and we’ll try and help.
