Check engine light...

[mellowboy]

I only used one O2. I had the shop clogged the second hole on the down pipe.

Well I took the knock sensor out of my spare block and replaced it in the new one and all seems to be ok. My ECU has stopped flashing me the 23 and all seems to be ok with my electrical system now. Now all I have to do is put my front end back together and have it inspected and I should be able to get my title for it. It's been a rough couple of months but i'm finally feeling like it's going to be a victory. hehe. Thanks for all the help!!

EDIT -- Nevermind, it's still throwing the code. It wasn't in the beginning but after warming it up and everything it's still throwing the damn 23. My idle also seems to be fluctuating from 1k to 2k after my engine warms up. When warming up it runs at about 3.5k RPM...does this seem high to anybody else? I know I need to replace my PCV valve because the one I have now is broken. But I still can't figure out this damn code 23...could it be because it's not wired with shielded wire??

yes, shielded wire is a must
