I'll be doing troubleshooting this week. And my o2 sensor is so stuck in that it is stripping.. it was stripping on an o2 socket so then I went down to a 21mm deep socket (after cutting the wire) and hammered it down to then out a lot of pressure and just have it slip again.. this is after days of pb blaster. So I need to take it to a garage to have them get it out.... not much else I can do. But will update on my troubleshooting that will probably be happening tuesday
