Asked by Apr 17, 2015 at 12:14 AM about the 2002 Dodge Ram 1500 SLT Plus Quad Cab LB 4WD

Question type: Maintenance & Repair

I have a 2002 Dodge Ram 1500 4.7 and I have replaced all the plugs, all the injectors, all
the coils and it is still running rough.  My scanner keeps saying it's the coils, but they are
all brand new.  Could this issue be the computer? or something else?

More than likely it the computer

were the bolts that hold the coils in place rusty ? if so you may not be getting a good enough ground on them and that would give you a random misfire. remove the nut and take a piece of sandpaper to them .
