      check for vac leaks
      check all grounds
      make sure the ecu is seeing 12v
      verify idle air/fuel
      check cts

      start with all the regular basics.

      Grounds are good air fuel right on just put a new intercooler on didn't find any leaks in the piping but maybe I need to check again

      pressurized the entire system? If the vacs low all of a sudden Id expect something to be out of place.

      Check your compression.

      Any misfire codes? Let it idle , and pull each plug wire, the cylinder that doesnt change the misfire is the dead one. I ve seen bent valves on heads from hadling, there is always a valve open once the cams are in, and since there isnt a combustion chamber in the head...

      Bent valve would show on the compression test.

      You learned from it. Start your repair logic doing the easiest things first. At least you found it, i have a friend thet would still be checking wireing on the complaint.
