O2 sensor help

[jester1341]

this car is on the SLOW road to recovery....

i replaced my O2 sensor because of error 21. it was replaced about a week ago and i got it again last night:cry:

what else should i try

it seams to only give me the code when i boost some where over 8lbs[stock gauge for a little while longer] and after driving on the highway for an extended amount of time

Check the wiring for the o2 sensor clips, mine was bad and finally broke. Had to spend $6 and get a set of 3 wire weatherpack connectors from nappa and wire up my own connectors.

well i rewired it but i guess i could try redoing the entire length, but i doubt it is that easy the only stock part is right before the conector[about 2 inches at most]

i was thinking it was in the wiring harness or at the ECU anybody have this problem??

oh also sabotage, were you getting the error code 21??
