how do you know when your o2 sencers are bad what will the car do? my car drives like a have a trailer behind it jurking back and forth until i put my foot into it. and at idle the moter wants to die every once and awile but not all the time it only acts up sometimes???
The response time will be slightly slower here compared to other sites, (but the quality of responses is usually quite better).
The weekends are especially slow.
As for your problem...
Have you pulled the codes?
If power returns when you go to WOT then the O2s are suspect, but there are other issues that could be causing the problem.
Pulling the trouble codes may not tell you exactly what the problem is, but it should give you a running start at a proper diagnosis.
