Hey everyone. So I picked up this bone stock 99gst a couple months ago. It hasn’t ran right and sat for 4 years. I fixed all the miss fire codes and it still misfires. It has a egr delete and while running and misfiring i unplug it and runs and drive great. Ok awesome then leaving it unplugged it doesn’t start back up. Anyone have any ideas what to look for?
