From Lusty Kid:
I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.
Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.
When is the last time you change your harness. Can't remember??? Replace it. Good Luck

Try putting somw SEAFOAM into your tank. It either your O2-sensor, or EGR-valve. Alot of the time, SEAFOAM will clean these sensor up????

I would disconnect the battery for about 3 mins. Then drive it around tell the light comes on and then check the codes again by cycling the key 3 times. Have you put new plugs in? I have replaced my plugs 4 times tell I relized Dodge durango 4.7 and Magnums do not like platnium plugs. They will miss almost from the first time putting them in. Then I would go to Cylinder 3 and look at the plug. For the most part its either plugs on the left bank or Coils. all you have to do is pull the coil put the plug from that cylinder in the coil and ground the electrode out. If it sparks the coil is working if not then change the plug if it still dosnt you have a bad coil. The power steering switch is somthing way diffrent. The o2 sensor smells the gas and tells the computer wether its needs to back off on fuel or put in more. So if thats bad youll lose about 2 miles per gallon if you need more help go to http://www.dodgetalk.com/forums
They have always helped me or email me at email@example.com I hope 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!!

Tips for a great answer:
RepairPal Expert Overview:
The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.
