P0304, P0401, P0455 truck running bad
Hey guys about a week ago my truck started running real bad, down on power a lot, and very shaky at any speed or at idle, I went to autozone to get the codes and i got the 3 above in the title, I had before 0171 and 0174 and the truck ran fine and now that i got these 3 codes it runs horrible, any ideas if they are connected? i havent done anythign to the truck in the time that they came up so i assume its gotta be something connected. I do know i have a hose that goes to the vaccum hub thats split but it has been split for a while. any ideas what the problem is? its a 98 4.0 thanks.
