HAve you checked the fuel pump pressure? Also, I'm sure you realize the codes, random misfire, cyl 2. However, regarding the po316, I have found cases of the coil being bad and causing the rough idle, and a bad connection on the B+ wire at the coil. Check that and let me know what you find. Also, you may need to do a compression test to determine if there is a burnt valve.
Let me know what you find.
