Hard power steering

I have a 2002 Civic LX with power steering. When the car is idling, I can
turn it left or right with ease. When I rev up the engine, it becomes very
hard to turn in either direction. It will continue to resist my turning even
thought I let off the gas back to idle. I have to release the wheel turning
motion and then the turning will become easier again, until I rev the engine
where again it starts to resist me. Power fluid is full.
Any suggestions what the problem might be

 

see response on rec.autos.makers.honda, and learn about crossposting
etiquette.

 

Sorry if I offended anyone buy posting on two different groups. My previous
experience showed me that sometimes posting on only one group will not yield
any answers.

 

That's when you cross-post correctly, which you did not.

To crosspost, you manually type in the names of each group, separated by
commas, but NOT any spaces. Thusly:

alt.autos.honda,alt.autos.acura,rec.autos.makers.honda

....and so on. Clear?

It is perfectly acceptable to cross-post a message to two or three groups
that are genuinely relevant to your question.

It is NOT acceptable to post stuff like "GWB sucks"/"GWB is great" to
alt.dildoes, rec.nose.picking, alt.weird.politics, ott.forsale, and fifty
other unrelated groups.
