Aristo swap keeps blowing efi fuse
93 gs300 with aristo swap. Just put new shortblock in a few days ago. drove it for a few days then last night was driving down highway and engine dies. Ended up being efi fuse blew, replaced and blew again then replaced and made it home. What I noticed when I changed the fuse was that the car wouldn't idle by it self. Looked over wiring this morning and didn't notice anything wrong. Car fired right up, I drove for 15 mins and blew fuse again. Replaced fuse, turned ignition on and it kept blowing fuses. Let car sit for few hours and replaced fuse and it started and I drove it for 10 minutes or so and it blew the fuse again. What could be causing this? I have searched about this topic and a lot of people say o2 wiring, i checked it, and it all seems good.

I believe I fixed the problem. Two wires in wiring harness behind valve cover had little bare spots in them that were either touching each other or the valve cover. Let the car warm up afterwards and then drove around for 15 minutes with no problem. Hopefully this was the fix.
