Default Which 02 do I need?

I have longtubes and the 02's at the collectors are the only ones I have. The others were deleted in my tune so thats not why its throwing a code. After my recent tune the SES light was off. A few days later it came on again. I took it to Advanced and had it scanned. The code read as an upstream oxygen sensor. I am on rockauto about to order a new one, but I dont know which one to get. they have upstream ones as lefts and rights. Any help as to which one I need is greatly appreciated. Thanks

Don't bet too heavy on any O2 sensor staying out of
heater / switching codes on a long tube car. Some
codes just need killed.

I just had my car tuned and threw the heater circuit code. I swapped in the bosch 13111's and the code didn't come back so they worked for me. Also having the extra wiring got rid of the extensions which were extremely nice.

PM sent your way for getting those o2's for $96 total.

98 TA, thanks for the info in the pm!

I dont really need longer leads b/c I have them hooked up to the rear leads. My tuner switched the wires in the pcm so I could leave them hookd up that way, the front sensors plugged into the rear leads. Would a BOSCH 13444 be ok or sould I get 13111's anyway? Can I use the same ones on either side?

Rock auto is pretty high on shipping you might want to look around.

Don't leave amazon off your list. I just got a pair of 13444s
for $76 shipped. Some "closeout" place.

After doing some more reading I want to go with OE stlye sensors. My car was tuned with those and thats what I want to go with rather than bosch. Is Denso part number 234-4025 the one I need or is is 234-4087, or one of each? I am pretty sure the 4025 is what I need but I would like someone to confirm this before I order. Plz help b/c I am getting shitty gas mileage and lots of .22 like backfires so I want to take care of this asap,Thanks.
