    Listen for a buzz when the key turned on not the car running. Then turn it on.and unplug the icv and see if the idle jumps super high idr what to exactly. You'll know its way to high.

      get rid of the injectors go back to stock

      test your tps with a multimeter, if it checks good then check clean your icv with brake cleaner.

      report back

          Spark sensor cable is supposed to be on cylinder 6, the one closest to the fire wall, farthest from the radiator.
