light is not on and i seems to run fine and i was lookin and found where it hooks up at

may have pulled the bulb out of the dash. i'd put it in definately going to hurt your fuel economy.

ok so the plug i thought was for it wasnt so i cant find a plug for it anyone know if this year 350 has a o2 on the header or manifold?? or is there just one right befor the cat??

so you do have the wire harnes with the plug that would plug into the o2 sensor?? it so then i would def. buy one to put in. you would deffenitly. notic a diff. and you would have better top end and like JEREMIAH said better gas milage

if it is a tbi you should have one after the cat ...mytruck has 4 o2s one before and after the cat

no i cant find the plug if i even have one im sure the headers i have will fit a lot of 350s so i dunno if its needs a o2 there

yea might not but most all tbi's have them to measure if its burning to rich or when to defuel the motor and to make sure all the fuel is being burned

well im guessin it has to have one cuz summit sold me 2 sensors so fuck if anyone has a tbi 350 could you go take a look and maybe take a few pics to show me were the plug goes thanks fuckin tbi shit wish i could pull it and put old school shit in it and be able to make a hell of a lot more power and look cleaner too
