I WOULD TRY AND RUN A BOTTLE OF SEA FOAM THOUGH IT BEFORE REPLACING PARTS. YOU CAN GET SEA FOAM AT ANY AUTO PARTS STORE FOR ABOUT $9.00 A CAN.

Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.

Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

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!!
