One more update:

I just replaced both of the original 02 sensors with the new replacements. I did a back-to-back test with the engine hot and the new sensors leaned the reading out ~another .3-.5 and dramatically stabilized the readings.

If this helps any, I just ordered 4 more sensors--two each for the Chevelle (already has 02 sensor bungs welded in the collectors) and for the wagon (needs bungs installed).

I've already purchased two additional harness kits (2 harnesses per kit, one for each sensor) so I can permanently wire then into the Chevelle and the wagon--all I have to do is disconnect the meter from the test engine and install it in whichever vehicle I need.

I am more than happy with this unit. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
