i have a 3sgte swap done. Everything is stock + FMIC kit + HKS BOV. I just installed an AEM UEGO wideband and the gauge is telling me im running rich. What can cause this problem? I know it can be bad in the long run but how do i adjust?

stock injectors as well? reset the ecu and if possible, get a new o2 sensor. Also make sure tps voltage and resistance is correct. Next, check coolant temp sensor.

What are your AFRs? There should be a coolant temp sensor for the ecu signal and one for the gauge cluster. Which one is bad?
As for the TPS if you check out the BGB, you need a feeler gauge. You put it between the stopper on the throttle body. And ohm out the different pins on the TPS. It could be the o2 sensor. -------------------- 98 Celica gt red- totaled deer

5sfe coolant temp sensor uses the same plug.

I would avoid driving it until that is done. hopefully that will be the end of it.
