Honda Accord 2.3 Engine is ULE Vtec, Did an engine swap. Replacement Engine idles smooth. When I step on accelerator it revs and dies immediately. If I hold the accelerator at any given place, example 2000 rpm the engine fluctuates wildly and then dies. All sensors and switches, wiring, distributor, fuel injection manifolds and plenum, egr valve and all other components which were working properly on the engine that was replaced have been reinstalled properly. The job was being done as if it was a long block replacement. I replaced the original engine because it was knocking and running only three cylinders. When the car came into the shop the car ran on three cylinders and could be driven down the road. Now with the replacement engine the car cannot be driven at all.
