well dam. This sensor has only a few thousand miles on it which brand would yal recommend

 

The last O2 sensor is throwing a code because its seeing the same a/F mix as the front one. It thinks the cat is broken because the excess gases aren't being converted. Add 2 cats and your torque will come back and codes should clear.

 

 

Put a cat and a muffler back on the truck.
I test drove a 98 360 with the same problem: GUTLESS.
straight piped, 2.5in piping, 35in toyos, 5in lift, everything less stock.
You mash the pedal and it went nowhere....
Last craigslist truck will ever look at.....

Needed 2 grand worth of work to make it anywhere near my current truck.

Glad I paid 6500...

Recap: Suck it up, replace the sensors, put a high flow cat in at the very least.

BTW, 4.56 gears too.
That would help I would presume...

 

BINGO, beat me to it.

Get an O2 Sensor SIMULATOR for the second O2 sensor. THen you can run no cat:

75 bucks and you will never have to replace it. I think that is cheaper than the O2 sensor.

Keep the old O2 sensor and splice the connector to the simulator. I did that with my 1996 with no cat.

you're welcome!!!
