SOURCE: lost horsepower on 94 Lexus LS400 after warm up.

O2 sensors WILL NEVER CAUSE A LOSS OF POWER, u are looking in the wrong place, sounds like a fuel starvation problem or a defective MAF, the O2's are just seeing this and setting a code..

SOURCE: MY LEXUS IS200 SE engine management light came on

What was the code? lean mixture? If so make sure there is no leak in the exhaust. I have worked on a lexus suv, but it was an 89. It had a lean mixture code. After examination I noticed a exhaust leak which was not apparent at first, there is a section in the exhaust the is very thin, and prone to leakage, causing the lean mixture code.

SOURCE: i need to know exactly

Hi!!
"V" Type Engines (V6, V8, V10, V12) are divided into 2 BANKS, BANK 1 is the side where spark plug #1 is, BANK 2 is where the Last spark plug is. Usually the #1 plug is in the driver's side of the engine.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

bank 1 is the side cylinder 1 is on.sensor 1 is the first sensor in the exhaust on that bank from the manifold.cylinder 1 is the most forward cylinder on the motor when you look across the motor at the front of it to see which head/vlave cover is farthest forward.
