For a long time, I have been getting 0300 codes . The truck has about 130K on it. I have changed the wires, pluds, two O2 sensors, distributor cap, rotor, fuel injection system to the upgraded spider. The truck drives fine, them stumbles for a few miles or so. After a while, the SES light comes on and the engine drives fine. After a while the SES turns off. then again in a day or two it comes back on. I have taken it to a mechanic with 20+ years of chevy experience and he has done most of the work. He can't figure it out anymore and dosen't want to see the vehicle again.
I would rather not sell the truck but since this has been going on for about a year, I have reached a level of frustration......
