Ok well I recently bought this car and on the way home the CEL light came on . .. p1128 (Lean condition)
The car had a blow off vavle on it which i already got rid of and put the stock dv back on.
I replaced bank 1 sensor 1 o2 sensor. Light came back on. . .
Now the car runs very rough when first starting it up . . almost sounds like it wants to back fire or something. idle goes up and down by a few hundred rpms . . Than it just smooths out.
I need to have this car emission tested by the 11th . . . Please give some usful info, suggestions, advice. . please. . Thank you
