The 4.3 uses a set of injectors with a metering body as all one piece that requires the upper intake plenum to be removed to access. Even then they don't really come apart to clean very well. I recommend using Sea-Foam cleaner available at most auto parts stores. Dump it in the gas tank with at least 8 gallons of fuel. Do this twice and if you still have a problem and are positive its an injector, get your wallet ready.
