  • Running very lean??????

    I just pulled all my plugs and o2 sensors while installing RKcrap headers and they are all very white. I know GM designed the V6 to run lean and be fuel effcient and low emmisions. Do you all also have very white looking plugs? I have also recently experianced hard cold and hot starting.

    They should be yellow-white, slightly off-white if they've got 20K or more on them and the car has been running right.
