85 nissan truck acceleration problem

[gtrr4]

Just bought an 85 truck king cab. Had to put a new radiator in it, so while I did that I changed the plugs, wires, and air filter. Then I went to drive the truck and I have a huge acceleration problem. Its like the A/F mixture is screwed up or something. I have the 2L engine. THe tappet cover says nissan Z on it. Truck has just over 100k on it. It ran fine B4 I did this work. Doe anyone have any ideas or suggestions on this topic? Thanks in advance.

its an 8 plug system. did you by chance get your intake and exhuast coil wires swapped? or worse yet get your wires mixed around for the two sides?
