Yeah. I'll double check in the morning. I've dealt with O2 sensors before, I know exactly what they do. O2 sensors don't work in a cold engine, so the computer runs open-loop until a few conditions happen...one is a certain operating temperature is reached, and another is the O2 sensors put out a steady reading. They dont read within the proper voltage when it's cold so the computer ignores them. Once they warm up, it uses a combination of MAF data, MAP (if these cars have these as well..I know older MAF Camaros had MAP's as well they just werent nearly as important), throttle position, and O2, among others, to calculate a proper A/F ratio once closed loop is achieved. Without O2 sensors, car would..hmm..PROBABLY run rich, since the computer would set a default which is probably the default it uses in open-loop operation.
