So the 04 Libby 3.7 started running like **** and basically wouldn’t even move and had to be towed. Pulled a bunch of codes that led me to believe plugs/coils were done so I replaced all 6 and cleared the codes. Now when I start up it runs fine when it’s cold but as it starts to heat up it just starts to run worse and worse and once fully warm it can barely run at all. It’s throwing code p0172 now (bank 1 rich) and once it starts to run ****** you can unplug any of the coils on the drivers side and it doesn’t make any difference to how badly it runs and if I unplug a passenger side it will **** the engine. No obvious loose connections or vac leaks.
