I have a 2005 Dodge Durango 5.7 hemi that is multiple misfiring. It is rough at idle and at average speed but once you hit like 2200 rpm it is fine. It will die anytime you stop as well. We have changed the egr, all spark plugs and wiring, cleaned the MAF sensor, replaced O2 sensor.

It it has thrown fuel too rich, and cylinder 2 misfire as well but now only code it is throwing is multiple misfire

 

could be timing??????????/

 

Having very similar issues with mine. Misfires and runs rough idling most times, Someone tested the control box and said it wasnt outputting in certain spots and needed to be replaced, The part was $225 and it hasnt arrived yet but im hoping it fixes it as ive put countless dollars into similar things you have. Ill let you know

 

I haven't gotten any codes yet, but I can she aint running right. I replaced the plugs. Changed the coils and wires with MSD Blaster and 8.5mm wires. It got better but I still have a rough idle. Seems like a misfire as I am cruising and give it gas. if I lay into it there is no hesitation and she goes.
