1990 Buick Century Limited 2.5L Cuts out, MIL Lamp on
Tried a new fuel pump, new oxygen sensor, used ECM, and new injector and a known good regulator. It runs good in open loop as soon as it goes into closed loop the O2 goes to lean and stays there until the light comes on and goes back to open loop and runs fine...
