O2 sensor is crazy
 

i keep getting a code 1 since i rebuilt my motor, i have even put a new sensor in it, not a autozone el cheapo either i put a honda sensor in. u can clear the code and as soon as u start it it comes right back. has anyone else had this before?

i hooked up the scan tool and checked the data list and found that my iat was telling the ecm that it was -33 degrees, replaced the iat and drove it this weekend from N.C. to atlanta for NOPI and had no more cel!!!!
