I'm not really sure whats wrong with it it just started doing it a couple days ago, If I drive it around for more then 20 minutes it will start bucking not very much just every 20 seconds or so, then it will stop for a little but then do it again. its getting fuel but i'm thinking its possibly icying up, or maybe my new modules failing. GM HEI 4 point module (cause i heard they can go out as well, but could it cause this?)
