Okay, so in my 86 SC, swapped from 2.8 auto to 305 TBI 5 speed, Used complete wiring harness from the 91( and by complete, i mean everything, from turn signals to tail lights, including a dash and colum swap)

Its got a few electrical, and a few other small issues, but im geting them worked out, with the battery hooked up, it kills the battery in about 5 minutes(without the car running) and it seems it has a bad connection or ground(turn signals and park light stay on, on one side of the car)

Another issue is more TBI related, complete engine/tranny wiring computer etc, came from a 91RS, ran great, idled fine, but now in my car is idles around 1500, and when warm, dosnt go any lower still.

Got any ideas?
