Its not really connected to this but i got a question since were on power steering… Am i just noticing this now and all s13 are like this or is it a new problem on my car. The power steering helps turn the wheel easy but when i move the wheel really fast back and foreward it seems like its now working properly like its not gettin enough pressure quickly enough. Its not noticable in regular driving but when I take a sharp turn at speed and gotta turn the other way for another corner going the oposite way the wheel gets stiff like the steering assist no longer works for that moment then with no string wheel movement it gets back to normal like the system has pressure again. any ideas? its really annoying as it messes up my intended steering pattern.

yea i know what you are talking about. haha
