svc light on

[birdflewby]

Just bought an 02 ws6 with a procharger. Previous owner said the engine light came on and Autozone said it was a o2 sensor. He replaced and the light went away. I have only drove it about 150 miles and the light came back on . Autozone checked it and said it is running too rich across both rails and suggested Seafoam. ????

Check your plugs to make sure they are NGK TR6 or one step colder plugs and gapped correctly at (.35). Then I would get the tune checked out by a reputable tuner like Livernois or somewhere else of your liking. I would not trust my car with some dude who knows how to an OBD II code checker from Autozone. It is better to be rich than lean though...
