P0172 96 coupe DX
So I have done a few bolt on mods to my car, CAI, full exhaust, y8 injectors, fuel rail and FPR. Those are all that pertain to the engine. I keep getting a P0172 code. I clear it and it come back on in a few days. I have replaced the upstream O2 sensor with one from a y8. The down stream O2 is new but for a y7. Timing is dead on at 12 degrees. Fuel pressure is correct at 32psi. I am saving for a p72 ecu and S300 install and dyno tune. Any ideas as to how to fix this light for the time being. I have thought about advancing the timing some but havent yet.

So you are running bigger injectors now without a tune and getting a code for running rich. Put the stock injectors in or get it tuned.

I am working on getting the money together for the S300 and dyno tune. I was wondering if there was a temporary way around this such as advancing/retarding the timing.
