Have '91 burb with 226K miles. when I engage cruise sometimes it holds and sometimes not.
when it does grab it usually only holds for few seconds then slowly loses speed. If I tap the gas it will come back
but again only temporarily. I replaced all the vacuum lines. What else might it be? also is the servo electrical
or vacuum? Thanks
