hi all,

is there a way to adjust fuel/air mixture ratio on a stock 2.1 WBX?
my van seems running a bit lean (tail pipe is too clean nothing on it) -
rebuilt engine (3K miles) - new OX sensor, new AFM, new Temps2 sensor, new
plugs and cable. new fuel filter and fuel pressure regulator.
should I wait till the engine has at least 5K miles and will see?

thanks

dan
