crazy idle problem!!

[reptilla]

well i have a problem that alot of people seem to to have...when cold my truck is fine once it warms up it idles eraticly and seems to stumble a little. every tbi chevy i have had seem to have this problem to some degree. whats the deal why is this happening???

My idle isn't eratic, just real high. When its cold out truck idles at 1500 rpm, almost as if vacum leak somewhere.

Check your vacuum lines and check you TB gasket.
