I just got done replacing the power train in my 1988 Jeep Wrangler It is a 4 cylinder 2.5L TBI set up. The list of new parts is a complete long block with all new internals including the head, water pump, alternator, fuel injector, fuel pump, fuel filter, plugs, wires, cap, rotor, royal purple engine break in oil. After driving for less then 50 miles on the new motor it started to bog down at load. When I give it gas off the line it goes until about 2000 rpm then it starts to bog down like its not getting fuel or air. I replaced the new fuel filter with another new filter to make sure that wasn't it. So now I'm thinking it may have something to do with EGR or map not sure hoping someone can help. Hope I've listed everything you need to know to help sorry if I missed something. Thx
