Today on the way to work, my steering started to act like the car was off (really stiff) as I was turning right (from a dead stop).

Did it a second time as I was turning left (again from a dead stop).

I checked the PS reservoir, and the level was fine, tho I didn't get a chance to look at the color or smell it to see if it was burnt.

There isn't really much else symptom wise. I was driving on the highway (65-75 mph) and had no issues.

It kind of feels like how in old cars if you turn off the ingition the steering like freezes for a second. But in this case I was able to force the steering wheel free (for lack of a better word).

Any ideas?

I'm hoping it's not the steering rack, I replaced that on my 93, and will never do that again.

Thanks in advance
