It's one bolt towards the bottom of the coil packs to unplug the connector and 3 nuts under the coil packs/icm to release the icm with the coil packs still connected. Switch them.
Your fuel trims are telling us that its really rich and pulling fuel to compensate, your inj. pulse is at 4 which is very high for idle, was this a spike during idle or a normal idle? If there was a vac leak, the car would be adding fuel or the fuel trims would be at +16 or so. Its also hard to tell until you get it idling normally. You might even want to give the GT injectors a try. The GT inj. are 33# and the GTP inj. are 36# or so, when tuning a top swap, if they don't put the correct tables in and your using higher # inj now, that would make it run rich. I am unsure if that would make it run THAT rich though.
