The A/F meter should be hooked to it's own sensor as per instructions .

If it's hooked to the same O2 as the computer, this may be causing a problem.


Check the fuel pressure if in doubt. The pump, filter, and FPR can cause problems.

High RPM power loss can be the first sign of a CAT problem, IMRC will manifest itself around 3800 rpm.

Is the rear O2 as new as the front?

... Thsi weekend while taking apart the intakes. I found that one of the secondaries on the front were nto opening. I fixed that problem and now the car runs great. A whole lot more power but the code still remains. What gives?

All 3 front secondaries are operated from the same shaft, so it's not possible for only one not to be opening. Might want to clear the computer and see if the code comes back. Also try swaping the sensors just to make sure it's not a flakey sensor or connector. If it's not a sensor problem, I would suspect a leak on that bank somewhere.

I am getting code 176 bank 2 running lean. I have replaced the o2 sensor with a brand new one from bosch and still the same [censored].
