Idle air control motor. On the side of the throttle body. Either real dirty or bad.

check your Throttle Positioning sensor that should fix your rough idle the TPS controls the breather on the front of the engine its affixed to the right hand side of the throttle body just infront of the spyder on the V6 Vortec 4.3L Models

you need to replace the throtle body controll sensor. Also you may want to make sure all your linkage from the pedal to the throtle body is cleaned and lubed correctly. While playing in this direct area. Your throtle body is only 4 bolts away. Why not get some carb cleaner and get to know your truck just a litle more.
If this is a carborator, then you need to turn my warmup idle down. there are 2 sets of idles on carborators. the one to warm up the engine, automatic choke or pin settings. Get a Chilton, find out which idles pin is for what. and play a litle bit.
I think you have a throtle body so I would also check the automatic air intake sensor. It could be going bad. Check your filter and make sure its clean.
hope all this helps.

Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located before the catalytic converter? The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!
