Ok so i have been getting my truck back to where it needs to be and now I have a new issue that is driving me absolutely insane. I had an extended crank for a while but I didn't have any CEL popping up. I figured that the problem had to be found in the fuel injectors somewhere and i turned out to be right. I replaced all 8 fuel injectors and the wires to those injectors as well. The truck runs great, idle is smooth as glass and its far more responsive, especially since i did the coil packs too. But the same day i change the injectors it gave me the P0171 and Po174 codes....I am going nuts. I'll test for a vaccum leak, but I doubt that's the problem. ANy help or any ideas would be greatly appreciated!
 






Figured it out, I kept clearing the codes and every 30-50 miles they would come back. Well I reset the entire computer and it solved the issue.
