Hello guys. My 05 Hemi 64xxx miles is throwing a p0300 (Multiple Missfires). It has no power at low RPS and is breaking up. I have to stand on it and it takes right off. I suspected the EGR valve so I changed that and the problem is still prevalent. I was reading that someone changed their front 02 sensor and that took care of a similar problem. Im heading out in a few to pick one up. Anyone have any other ideas? Thanks in advance.

 

i would swap come ign coils around first if that doesnt hep then either do a compression check on each cylinder or pull the valve covers and make sure no spring is broken

 

I agree w/weed sounds like a coil to me...

 

I just went through a similar problem and it turned out to be the gas pedal assy - sensor was bad, bad pedals in 2005 to early 2006. See this link, perhaps it will help:

Just read through your thread. I definitely have the stumble if I stab the pedal real quick. I haven't driven it enough since the problem started to notice anything with the brakes. Ill try disconnecting the TPS like you did and see if theres a difference.
