These are idle readings?

What scan tool are you using? (I am curious about the 0.960 O2s...looks like its an otc4000 or similar?)

CCs were zero? at idle?

What chip are you running?

Hey Steve sorry it took so long to get back to you.yes those readings were at a idle,useing a OTC 4000E scantool the chip is a THRASHER 92 with anti-theft.

I don't see a fault then...not at idle. It is idling pretty rich but then the Thrasher idles richer and in open loop compared to most chips.

The 4000 will report higher O2s than most of us report here using Scanmaster, TL, DS, etc.

Those read .441 when the key is on, engine not running whereas the 4000 should report .500.

to convert o2s values we report using those tools, multiply times 500 and divide by 441. Or multiply by 1.133. You will get readings about 100 mv higher due to this difference. The Thrasher is a screwball chip in some of its codings so you may get some parameters that look strange on a scan tool.

Ya, best all around rule of thumb with the OTC 4000 is to just subtract 100mv from what you're seeing to calculate "actual". Not 100% accurate, but VERY close.
