I have an 84 pickup that had a 93 22re swapped into it. I hash the 93 engine, wiring harness, gas tank mounted in the bed, trans and transfercase. When I bought it, it ran great. Took it out wheelin went through a mud hole and started running like crap. Thought I got something wet and waited for it to dry out. I started up fine later idles great. after warming up it will still idle great run great at WOT but under a load it runs like crap. like it has the worst miss I have ever experianced. It hase new NGK plugs, cap and rotor. I dont know where to start on this. Please help I have a run to go on in less than two weeks. I really need this truckto run well.
