    Default 1987 gmc tbi

    Hi everyone, my 87 just started having tbi issues, everything happens at low idle or just rolling on the throttle,the truck mostly stalls , runs sluggish and shifts hard also pings when under load . the truck has 100000 miles on it ,the previous owner installed a holly tbi, model 206 . Well any input would be greatly appreciated......

    Welcome to the site! That is not very many miles for an '87. There are a lot of knowledgable folks on the site who should be able to give you some help. Good luck!
