More problems, PLEASE HELP!!!!
 

My car has been sick for a few wks now but I didn't really care bec I knew i was rebuilding the s/c, cleaning injectors, replacin gaskets, chngn wires, etc. I felt the problem would show up in the teardown. But it didn't so I had the car scanned yesterday and the scan showed a rich fuel and a misfire. So I had an xtra Delco O2 sensor sitting in basement and my Taylor wires came today. I replaced this stuff and still same problem. My current symptoms are: Loss of power, constant roug idle, only 100 miles per tank, and some backfiring, also exhaust sounds a lil louder. Ok guys what do you think? I use 93-94 octane BTW.

It's all those yellow components and home depot stuff.
