Steering
I have a 1998 C5 and the steering acts like a go cart, the least bit of movement and the car darts one way or the other. I just want to cruise and this makes it very annoying to drive. Any ideas?

I'm 73 and have owned several corvettes over the years but I've never had this problem. I thought that maybe I might have to lower pressure in the power steering pump. Point is I just don't know and all I want is a cruiser nothing fancy. Don't want to keep throwing money at it.

how many miles are on the car?
did you have them check the rack and pinion unit and the power steering pump. maybe valving in the rack and pinion is sticking (I need to read up on where the valving is on c5s) i think this could be it....this would create dartiness
lets read this together

I would also look to rear end issues and perhaps you are encountering rear steer.
so you want to make sure the rear has no free play in any of the parts.

Have you pulled stored codes through the DIC? If you don't know how to do that there's a good walk-through on YouTube.
The steering has a tendency to default to "high" (i.e., constant power being applied to the assist) when the system starts to read values outside of it's range. The very basic way to describe it is your C5 utilizes magna-steering which adjusts the power assist depending on the car's speed, and the SWPS (steering wheel position sensor) is a component of this. So if you're traveling at parking lot speeds you should have a lot of power assist (easy to steer and whip around). At highway speed there should be very little power assist as you're at speed and do not need "jerky" steering.
When the system reads constant values outside of it's range it will throw a stored DTC accessible through the DIC and potentially default to aforementioned value regardless of the vehicle's speed. There is a tendency for ABS and traction control to subsequently have visible issues but that's not to say the issue you are experiencing would create that situation.

i am an old school guy and the c5 is my first foray into the modern age...i drive new cars but let the garages fix them on the rare occasion they need it. I am absolutely amazed at the technology it has. i bought the c5 becsuse of the DIC and said to myself "time to get out of the stone ages" and make friends with the technology because i have become such a big fan of Fuel Injection and roller cams. i am absolutely enjoying learning how the mechanical systems are interrelated to the engine management systems

I had this exact same steering problem on my 98 and it turned out to be the new tires I put on (along with an aggressive alignment). Once I switched tire brands and had it realigned the problem went away.
P.S. The tires were BFG KDW2s

If I understand your post correctly, it did it before and and after you put new tires on? Did you use the same brand tire?
