Hello folks, I currently bought a civic with a b18c swap and thusfar i have not been able to finish registering this car because it wont pass smog (CA). p0170-fuel trim malfunction p0172-system too rich bank 1 I have been trouble shooting this problem for a while now and am completely stuck. Its running with a P73 A03 b18c5 ecu since the jdm one from the original swap wont connect to an obd2 scanner. Oxygen sensors read ok Throttle pos. sensor and manifold abs. press. both ok All 4 injectors read right under 12ohms (11.8-11.9ohms) Fuel pressure read ok around 49psi with regulator pinched then increased unpinched I checked valve lash and IN 0.006in EX 0.007in which should be ok I changed fuel filter That is why I dont know what to do anymore. The only thing I know this swap is missing is the BARO sensor yet I havent had any luck finding this at the junkyard.
