Hello if the van is shaking with a misfire and down on power I'd 1st suggest doing a compression test across all cylinders and check all cylinders are within 10-15 psi of each other if this is OK then I'd say 1 or more injectors are clogged and not flowing properly and its best to have them all removed and flow tested / cleaned by an injection specialist
