How is the car runnning? If there are no driveability problems it is most likely your O2 sensor.

same happend with my B18B in my EG......think it might be I wired the new O2 wrong or there is a vac leak somewhere.....read in a manual it has to do with fuel pressure/fuel regulator and poss vac leaks....when i change my TB gasket Ill check everything out and let yall know if it went away
