Help please...O2 sensor question Options

[celi_gt_racer]

i'm workin on a 94' st celica atm, and it has 2 02 sensors, one in the header and one later in the flex pipe. We're putting on an aftermarket E-bay header and flex pipe, and the header itself has a spot for the first O2 sensor, but there is no hole for the secondary O2 sensor in the flex pipe. What am I to do? will the car run correctly w/ just the primary O2 sensor connected.....is there any kind of trick to get this set-up running correctly. any help would be apprechiated, we're tryin to get this car on the road at the moment

Alright, so you plugged the 2nd O2 Sensor up and it worked? What did you do with the second O2 sensor? I have both screwed into my ebay header (I know, it sounds stupid) and I do have a CEL. What you did sounds very good to me, but how did you get rid of the second O2 sensor?

I tried to have my 2nd one relocated to the cat as well but no one would touch it.

yeah i tried having the 2nd O2 sensor right below the first one on the ebay header and it had the CEL on all time.. so right now the 2nd one is just plugged and only throws the CEL if I do heavy acceleration.

I am going to get a 2nd O2 sensor and weld it behind the cat thats under the car. I already bought a nut for it and will have a friend weld it on.. Problem is I bought one of those cheap universal ones and my friend won't touch it.. he said i have to buy OEM which is like $150
