I'm new to the forum and thought I'd post yet another thread on the wonderful O2 sensor trouble code.
My truck has been wonderful, I take care of it and change the oil every 3k.
In the last month I have replaced an alternator, power steering pump, (both belts along with each), and I just replaced my radiator.
I was driving on the highway three days ago and my truck had a hesitation in 5th gear...it corrected itself, but continued to hesitate...then fix itself.
Two days ago I went on the same route, ended up bogging down in 5th gear, had to shift to 4th....it bogged down in 4th, so I hit 3rd and floored it...it cleared it out, and ran like a top...but 4th and 5th now are really sluggish gears until it "fixes itself".
I have since changed my oil, used a can of seafoam in the fuel tank, Changed my plugs and plug wires (correct wiring) fixed a leak in the fitting connecting the air box to the throttle body, cleaned the throttle body and the MAF (twice). I then proceeded to drive up and inclined hill (nothing crazy, but it was an inclined paved road) and my tacoma almost died in 1st gear...
My check engine light came on (first time ever on this truck for me)
Yesterday (still having the loss of power problem) I attempted to remove and clean my 02 sensors. I snapped off one of the threads...fml...and was only able to get one nut off of each of the 02 sensors (the upstream sensor still has a nut that will not unscrew from the thread...its backed out to the top of the thread, but will not separate. My friend loaned me his OBD II, so I connected the 02 sensors back to the exhaust with two nylock nuts for a quick fix for a diagnostic.
I ran the OBD II this morning and it reported a code of P0133.
I ordered upstream and downstream Denso 02 sensors, and HOPE SOMEONE HAS SOME ADVICE!
I am moving from Oregon, back to Texas (supposed to have yesterday, but the truck is holding my move)...so I'm in a hurry, 2nd day air for the sensors...etc. Any advice is greatly appreciated.
