DTC P0131, 0133, and 0151?
 

hey everyone, im planning on purchasing a 98 firebird v6 but it has an LS1 swap. from what i gather, the motor's a 98-00 as it still has the EGR installed on the car. i scanned the pcm and got the 0131, 0133, and 0151 all related to the front O2 sensors. the car drives fine in both cruise and at WOT.

i did some searching on this forum and is it a possibility if the ECM is at fault? also noob question but ECM=PCM correct? the current owner did not do the swap rather he purchased it from the seller before him. i could go and replace the O2 sensors but if those who has done swaps before and had something like this happen i'd appreciate your assistance :cheers:.

from the log scans there were no misfires, a few KR at WOT but i imagine thats normal from factory.

Where are you located?

lancaster. why do you ask?

There is a car like that a few houses down from me (also from Lancaster). A few other cars in his driveway/garage? I have hpt, and a dyno. Maybe I can give you a hand
