Hi guys.. I bought a 94 Buick Roadmaster with LT1 5.7..Got it for the eng/trans. But it has the service engine soon light on. I would like to know problem before i remove the engine.Right know i can start it but it has a dead spot on acceleration . Tried to jump AB connector on plug (flash code) but light just stays on...Do i need a code OBD tool to read codes.. Any one ... its a hearse...
