can a bad o2 sensor cause lterm's to max
 

im getting a code for p1133 for the drivers side front o2 and also the lterms on B1 are maxed out at 25 at idle

could a bad o2 sensor cause the maxing out, or should i look for an intake or exhuast leak

well the car was running like crap after i did the heads and i atapped it and it showed maxed out ltrims at idle on bank1 and a bank1 o2 sensor code. im was assuming the bad o2 sensor was causing the high ltrims and the running like crap

so i swapped the o2 sensor and it runs like a champ

havent atapped it yet, i dont have atap, a friend does, but ill probably log a few runs on tues
