i need help with some codes
well as most of you guys know from previous posts my car hasnt ran right since my rebuild. it hesitates and misses once and a while at low rpm. enough to even make it backfire. i have changed every major related module, sensor, plug, wire, everything, and nothing fixed it. i finally ran codes.

543-fuel pump ckt open-battery to eca
koer
225-no knock signal during test
543-fuel pump ckt open-battery to eca
