I have a P1133 code but no SES light. Do you think this will be an issue with passing emissions when they do the OBDII scan? I did some searching but didn't come up with a definite solution. Should I try the replacing the O2 sensor(s)? Any suggestions or ideas?

how long has it been since it failed? the mil on a p1133 or p1153 will only turn on on the second consecutive failure. u can try tbrowing an o2 sensor on it. that is prolly the problem. it just means that o2 sensor is switching from lean to rich too slow
