allrighty then, so i put on a 4-1 header two weeks ago, of course i took my cat off.....i have no 02 simu;lator yet...just the 4-1 header...pipe and a muffler...the new header had one o2 fitting. so i just totally disconnected the second 02 sensor. the check engine light came on, i knew it would, it rean very well up untill this afternoon....the engine can barely run with out stalling out and the air/fuel meter is going back and forth betwen rich and lean VERY fast...i mean VERY fast, not like it usally does., do i just need a 02 sim for the second one....or should i just plug in the second one and tie it up somewhere....any help is greatfull!

hey man...which columbus? GA or OH? Im in GA......anyways....find a way to mount that second o2 sensor in the header.....you could burn up your engine if it runs too lean for too long.... and if it runs too rich too long youll have a nasty carbon build up and lose the HP you gained by the headers.

get it done right the first time......[IMG]i/expressions/face-icon-small-nono.gif[/IMG]

you can tie it up some where...but youll probably run rich.... so its up to you

carbon buildup- on the plugs? would that create the problem i was describing?

Just buy an O2 Simulator. That's what I did, and I have not had any problems yet.
