Anyone remove there exhaust manifold
#3
Your exhaust manifold? Very simple.. I don't think you need anything more than a 14mm deep socket, maybe an extention, small one for ease, and maybe a 10 or 12mm wrench.. Actually,
The picture to the right corresponds with the first set of instructions on it's left and goes down.. Prob. Don't have to mention that but so your not confused. Here ya go:

you are correct.. 02 GS430
already got the O2 Sensor out.. but the previous mechanic i think he welded the O2 sensor.. i had a hard time removing it.. but when i was trying to install the new O2 sensor it left some residue on thread
thank you for the info.. I just want to make sure i don't have to remove my engine holder and have to lift up my engine a few inches just to get out the exhaust manifold.. I have seen reposes on other thread that you need to unbolt the engine support
thank you for the diagram
Bank 1 Sensor 2.. read the code but do not remember them..

I'm pretty sure you don't have to remove your exhaust manifold, If your concern is you can't install the new 02 sensor because the thread is damaged. All you have to do is buy a rethreader and clean out the threads. Trust me I doubt the previous owner welded the old 02 sensor on.

im probably the best person to answer this question as i just replaced my entire exhaust manifold on my 01 430 because it was cracked and leaking air making an annoying farting sound. Before that I changed my O2s and NO you do NOT need to remove the manifold to change them. Everything is easily accessible from below the car and the rears i believe you need to remove the floor liner. You ONLY need to remove the manifold is your changing the manifold gaskets NOT for O2 sensors. And to do that you need to tilt the engine out of the car its not that big of a job but its pretty annoying. Last but not least you MUST MUST MUST use OEM O2 sensors no matter what the price is. Find out which Denso part number it is and order them from amazon. All lexus does is sell you the same one Denso sells with their name on it for double the price. with OEM O2s you are guaranteed to have no more issues...

Get some Denso Sensors on ebay, the #2 Sensors are quite easy. Had mine changed a couple of months ago on my 01 gs 430. you don't need to remove the floor liner, just pull it back from the front until you feel the cable, then find the plug near the middle and the clamp on the floor.
For your thread problem, its propably just a worn thread, get a rethreader.

Oh man my bad, dammit and I took all the time to finding that on ALLDATA, sniping, and posting for it to not even be the same car... Lol! Let me see about the 430,...... ...... dam I want a 430! Must be so sick!

Here's a technicians note: Bank 2 sensor 1, 2 HINT:
-Before installing oxygen sensor, twist sensor wire COUNTER clockwise 3 and a half turns.
- After installing oxygen sensor, check that sensor wire is NOT twisted. If it is twisted, must remove the sensor and reinstall it.
Don't know if that applys to you but maybe it's twisted hence why it's still bringing up the code? Hence why they put this Technicians side note?
