bogging

my friend is having problems with her civic... when she hits the gas it bogs and is unresponsive before accellerating. Any ideas what could be causing this? it's an auto tranny.

After it boggs does it accelertate??

yeah

My crx does did that too i would go and floor it and it would bogg then haul butt. I took it to a import shop and they told me it was the o2 senor.
