Rich Idle, Lean Cruise?

[RunawayValet]

I switched them it runs worse. It actually makes the rear trim decent but thw front is like -25. I cant even really accelerate it just breaks up so bad.

trims should only go to +- 12.5. what did adam or brett say?

[RunawayValet]

Adam said the different emissions spec cars were switched. Even thoughbi am pretty sure it is fed spec. He had me switch it in the flash program but it only made it worse. I need to call adam today and ask about-25... question do the o2 sensors do ANYTHING when your at WOT?

[anyonebutme]

While the O2 sensors arn't used at WOT, your trims are.

UPDATE So I actually bought a new o2 sensor, and while removing the old one I found that the wires had touched the manifold and melted three of them together. I fixed the wiring. Now I am getting decent trims. Lows are ~2 AND ~1 AND mids are around 3 and -3. However according to the wideband I am still running pig rich on the rear bank and about 4 points leaner on the front. Even worse is that I am still getting this terrible breakup around 5k RPM, at any boost it breaks up around 5k unless I am sitting idling.

Plugs are gapped at ~28 and are NGK bkr7e remember this is e85. Its hard to tell which bank is correct... the lean front or rich rear.
