Hello I'm fairly new here, I've read a lot of helpful stuff on this site and hope to get a little help. I just recently replaced my bank 2 sensor 1 with little to no problem aside from breaking it loose. I knew I would have to replace the bank 1 sensor but kept putting it off and the other day I got the cel with code for bank 1. I knew it was coming because it was idling rough and similar symptoms from before. Today I decided to replace the bank 1 sensor as I could not eccelerate at all. My problem is when I removed the sensor I ended up stripping the threads in the hole and now the new sensor wont easily screw in. What can I do to fix this problem without replacing the pipe it screws into?? Thanks in advance for your advise and sorry if I posted this in the wrong place. Its easy to get lost on this site
