B18B1 with turbo. SAFC2 for fuel management. The car ran fine before I took it down and added a wideband O2 sensor, and EGT gauges. Now as soon as I crank it, 5 seconds later the CEL comes on and stays on.

I didn't change any wiring from the SAFC2. With the CEL on, when I let off the throttle the engine immediately runs lean until I put my foot back on the gass. Also when I try holding it at a constant RPM, it bogs down and then comes back. When it bogs it runs lean for a second until the RPMs come back up. Car revs and drives fine, just the damn CEL.

Any suggestions will be greatly appreciated

Thanks.

pull the code and see what's wrong. When you added a wideband, did you disconnect your factory o2? or did you just tap another bung?

i have the same problem and im not boosted

when u floor it it bogs for 2 seconds and comes back but only does this once every startup
afterwards u can floor it as often as u want right?

found the problem, the code was a faulty coolant temp sensor. It gave me the cell because I tried tapping into the line with my VDO temp gauge. Problem solved. Thanks.
