ok guys new to comp Diesel but I need help from you experienced diesel tecks. So here it goes I have a 07 dodge 6.7 an one day it started missing a little an till I made it home from work it had gotten worse an threw the cel p0303. Next I switched the injector from cylinder 3 to 4 an it stayed at 3, but when I started the truck up after doing that the rail pressure ran out of control it was like 27,000 at a idle mean while the truck is still missing. So I called a buddy that has a snap-on computer to scan it but when he came the idle dropped way down it was fluctuating from 4,000 - 7,000 still missing. And he thought to changed the cp3 so my brother has a 08 all stock 6.7 an he let me brorrow his truck for a week I switched the cp3, cam sensor no change it was still 4-7 at idle. but the last time I fired it up it starting running wild again. After being pissed off I figured that it wasn't nothing I changed so I was going to put my brothers truck back to gather an pull the head off my truck cause I think my heads cracked or a intake valve seat is bad. After putting his 08 back to gather it started up idled fine an then I got in it to take it home an it had no power so I put my edge cts on it to look at the rail pressure an it said 11,000 at idle an to the floor it only hits 13,000. So it was fine before I swaped the cp3 to my truck an back so my question is to you guys how to fix it an what could be wrong with mine cause I guess it messed up the 08 cp3. Im just out of option an now I have two broken trucks on my hands.
