A few places to check.
Clockspring in steering wheel
Connection to cruise module under driver side battery. Also the cruise module and vacuum lines are often damaged from battery juice.

Welcome to DTR

 

thank you i will check into that also would having oversize tires effect this in any way

 

No, oversize tires are not an issue.
fueling around offers good advice, however when my clockspring went on my 98 I also got an airbag light

 

that light hasnt come on i mean at 162000 miles i gues stuff just gets old how hard is it to fix this problem and will it be a huge ordeal to fix or do i need to take it into the shop?

 

Switch contacts can get dirty also. Used compressed air and blow around the switches....

 

Seems like I've a similar problem for years now. In cold weather only (all is fine during summer months) the cruise sets on target, but then increases speed to well above the speed limit (actually been ticketed once because of this). The only way I can beat it now is to set it well below the speed limit then drive at higher speeds for 5 to 10 minutes after which I can reset the cruise to the desired speed. To date, I haven't found a solution to this. Also, about 2 weeks ago the CRUISE idiot light on the dash no longer lights, but the cruise continues to work in the manner described. Perhaps someone may have some hints/fixes about this behaviour.

 

i would take that problem anyday mine just wont grab and hold
