Let me add that my DJ code WBX has an additional lambda ECU and the
engine did not originally come with an O2 sensor. I have not detected
any difference in engine operation with or without this ECU.

Also, the engine now is quieter. It had an angry edge to it which is
now diminished.

 I also eplaced the idle control valve which was apparently bypassing
some vacuum. The icv and the injectors are the only variables.
