ok, i have 99 civic SI with turbo and i was drving to my moms house and i was pressing the gas on my car and it was weird the rpm's were lowering real slow and then the car jerked back and when i got to my moms house i used my odb2 reader and the code was

P0132 02 sensor curcuit high volts (bank 1 sensor 1) and now my car kinda idles funny and does that jerking thing.

 

take out your o2. maybe its dirty, clean it and see what happens
