Can't accelerate above 30 mph.

I had a similar problem on my 93 Accord after I accidentally threw the car in reverse at 50 mph, obviously wrecking the transmission. When I got it rebuilt I was told the transmission pump was to blame (clogged with "shrapnel"). I, and your car manual, recommend taking the car in to get the tranny looked at. Especially considering you just had the fluid changed which is what would normally cause the problems you are describing.

a bad or disconnected oxygen sensor will make the engine run rich.
How about a clogged air filter? 

SOURCE: RPms increases as im driving or when I let go the accelerator

There are two solenoids on the front of your transmission one controlls the tourqe converter .try tapping them with a screwdriver handle the screens in them might be plugged or you might need to replace them

Cvt transmission is continuously variable transmission. VSS is vehicle speed sensor. A faulty sensor can make the transmission run erratic.
