Have you ran codes on it yet? Clean your MAF next.

i ran the computer no codes show up

im also gettin alot of gas and liquid out of the exhaust

i cleened the o2 sensors by soaking them in carb cleaner then making sure theres no carb cleaner on them before you put them in

then i just sanded them down

Sounds like it's starving for gas not running rich. Any black smoke out the t-pipes?

Dude you cant clean o2 sensors! Check your MAP sensor if you dont have a MAF, sounds like a load sensor problem to me. That liquid coming out of your exaust is water. Its a by product of the catalysts working.

My car runs rich...to the point if I start it in the garage it loads up the house with fumes. Or if I let it idle in a parking lot with people their eyes will burn in a matter of seconds. I've replaced 02s and ECT sensor, cleaned everything...and no better. I guess I need a tune...with stock MAF, TB, injectors, and an A9L [:'(]
