need tune up what could it be
ok here's what I got. The following is a list of parts that I installed recently, ran fine untill recently
-distributor cap & rotor
-MSD coil and wires
-spark plugs
-checked timing
-O2 sensor
-water temp sensor
-thermostat
Car has started to idle rough, I pulled a couple plugs and they don't look good. They have black soot on one half side, what could be causing this? I have a 91' Camaro w/TBI, I understand that I can't adjust this on my own because they came sealed from the factory. Could it possably be that the Throttle body needs adjusted?

First thing I would do is check the gap on your plugs. Put them to the specs that your car is suppose to be set to by the book. As for the timing, well there is a mark on my intake and distributor. All you have to do is line up the mark and you should be good. Is there anything else that you did besides what you stated? Try this and let us know what happens
