Ok,heres The Scoop. Just Got New Ip New Ops New Pmd And New Lifter. Problem Is I Am Getting A Small Hiccup At About 1800rpms. Only Happens Sometimes Not That Often. After Going Through The Ip Thing I Just Put All New In Except Injectors. Could A Bad Injector Cause This Or Could Air Be Trapped In Line. Otherwise Runs Like A Banshee!!!

Could be a restriction in the fuel line (trash) or weak voltage through the OPS.
