New power steering pump stiff to turn

Hi Guys,

I'm new to the forum and love my 2005 TSX. I replaced the power steering pump last weekend because it was leaking and flushed the system. I've also had the recall done to replace the power steering high pressure hose.

Now the majority of the time, the PSP works great. However, sometimes when I'm driving slow, like parking, the power steering will be stiff. I'm thinking there might be some air in the system and I need to flush it again.

Any suggestions?

Thanks,
-Mike
