Went over to Armon's today to finally work on his 929 after it sat for 3 years because the transmission and motor died. We pulled the transmission, drive shaft, and cats off. All that's left is to pull the motor and wait for the cool replacement to arrive to have even more fun. Then we came back to my house and put on the rotors and pads. Hopefully tomorrow I can put the alternator from my good motor on and see if that fixes the rough idle. If not, the adventure of finding out the rough idle continues.
