Answer

well if it is bogging down i would verify that the exhaust isn't restricted from a clogged catalytic converter...if ok then test fuel injector with a meter to ohm them out...this engine had terrible injector failures due to bad electrical windings they need to test above 11.5 to be considered good...also check the hose coming off the fuel pressure regulator as they sometimes have a ruptured diaphram that causes raw fuel to enter the intake and cause running problems..lastly the EGR valves on these engines tended to get very dirty sometimes stopping the pintle from full closure which in turn equateds to lower manifold vacuum that the ecm(computer) translates into the wrong fuel ratio because of the bad MAP sensor reading...also causing poor running condition..please remember to use the green accept button - thank- let me know if i can further assist you
