o2 sensor - 5/8/2008 11:03:44 AM    Fnix   Posts: 52 Joined: 9/19/2007 Status: offline What is the o2 sensor exactly? What will happen if I remove it? I wanna put in straightpipes or cherrybombs without messing with the o2 if possible. I will be taking everything from the stock headers on through and replacing with custom. Post #: 1

Without it the engine will run bad. You can get pieces to use it in a modified exhaust system. < Message edited by moparborn -- 5/8/2008 6:47:11 PM > _____________________________ (in reply to Fnix) Post #: 2

Any extra air in the ex. system can make it run fat. The computer will add fuel to compensate for the extra oxygen. _____________________________ Things I wanna research someday: ''Sore as cancer on an ape's ass.''

Surely somebody has done what your doing on a OBD I 1st gen truck...anyone? _____________________________ '91 D150, standard cab, standard bed '63 Rambler American 330 (in reply to lugnuts) Post #: 4

RE: o2 sensor - 5/9/2008 7:24:27 PM    nemesis_SS   Posts: 316 Joined: 1/21/2008 Status: offline i guess the exaust sorta comes in 3 or four parts. First is trhe exausht manifolds, which run to just past the firewall and become all one piece, and the 02 sensor is in that on the drivers side. its hard to find you need to get under the engine. then they join at the colector or watever which has a short piece running to the cat, then another peice to muffler, then tailpipe. Anything after the manifold can be manpulated without having to make any changes. really you just need to make sure the headers you buy have a socket for the o2 sensor. so to answer your question, as long as yopu dont have emissions tests where you are, you can go right from tailpipe to muffler to cat and do watever you like but no changes after the cat unless you make sure you can stick a sensor in em. newer cars have as many as 4 o2 sensors. "upstream" ones are usually after the cat, and "downstream" right in the manifold. if your gonna hot rod the thing just rip everything off and go to  carb. < Message edited by nemesis_SS -- 5/9/2008 7:33:10 PM > _____________________________ '91 D150, standard cab, standard bed '63 Rambler American 330 (in reply to Fnix) Post #: 6

RE: o2 sensor - 5/9/2008 8:11:17 PM    lugnuts   Posts: 487 Joined: 2/1/2008 Status: offline   What I was getting at was to use quality headers/manifolds with the o2 bung in 'em if you decide to replace 'em. Cheap headers have thinner flanges at the heads, more prone to blowing gskts.  o2 bungs are available separately to weld in the pipe if that's where your factory o2 is. Do a good welding job at all joints close to the mtr.  The manifolds are ''upstream''. < Message edited by lugnuts -- 5/9/2008 8:22:27 PM > _____________________________ Things I wanna research someday: ''Sore as cancer on an ape's ass.''

Status: offline You can buy a strap clamp that has a bung already welded on,just choose a location,mark and drill your hole and tighten strap in position. You can get collector reducers with bungs as well. < Message edited by moparborn -- 5/10/2008 7:50:01 PM > _____________________________ (in reply to nemesis_SS) Post #: 9
