Everythings back to normal.... 1993 Mustang lx

It happens that I was indeed out of gas. The computer from the yard works great so I have an extra computer. I only have 1 extra IRCM. The one I put in my car was bad. It made my car idle low so I had the idle up so it wouldn't shut off on me. I went to test my injector to see if it was working by unplugging it and seeing if it ran different. It did so I started to tap on things. I got to the IRCM and every time I tapped it, it rev'd up and I heard it click. I'm thinking the a/c relay was shorting out cause I switched it back to the original and it's back to normal. Now it drives with the a/c on. So i'm going to do the muffler, paint and interior and thats it until I find a 2.3 turbo. Maybe some new seats from another year mustang like 94' and up. What years can I use them from? And i'll do the 8.8 rearend with posi traction.
