I have a 2007 dodge Charger 5.7 Hemi. I have come into a problem first I had the 1 and 7 cylinders misfiring. So I took it to my guy he found that there were mice ratting my wirers. So he fixed it changed 4 coils. And gave it back within 5 min. of driving they ( cylinders 1 and 7 started to misfire again so I just turned around and left it there. 6 weeks later they have changed the computer cleaned the throtel body ,changed the lifters and springs also the regulators. They have no more answers. So I'm stuck. Please help me.

 

It is also only coming up as cylinder 1 misfire not both.

 

You can ask the guys in the Charger section as they may be able to help you better than the regional section,
