Hello,
Ive got a little bit of a problem that needs some advice. I installed a greddy evo2 cat back and test pipe onto my 99 ex awhile back, and have just been living with my cel light on, but im selling the whole system and today I put my original exhaust on and I am still getting the code. Also, I did disconnect the battery, and let it sit for awhile to see if it would reset the ecu. Did the whole 3 times turn the key to on position and it didnt work. Also, I was driving for awhile with just headers, and the o2 sensor came loose from where I had fastened it and is banged up pretty good, i mean the actual sensor part of it is kinda bent and stuff. Im assuming this is my source of my cel, seeing as nothing else has been changed. I was wondering, if I buy a new one off of hondaautomotiveparts.com or something, its going to be like $188, if I do order this, how do I go about installing it? Do I just have to snip the wires and solder the new one on or what? I tried to get a o2 sim to install, but couldnt figure out where to plug the thing in. Thank you!

 

Please, could somebody help me out. Im wanting to order this tonight so I can get this problem resolved next weekend if I install it. Should I buy the expensive oem honda one, or a bosch one or something off of a website for like $50. Either way, how do I get to the plug to replace it?
