94 chevy no power

Do you do all the work on your truck? This sounds like a problem that may take some testing of sensors, your fuel pump pressure. Start out getting a can of carburetor cleaner, spray along the intake & heads, front and back of intake, and base of throttle body. This is cheap and eliminates vacuum leaks. Things that make the engine use more gas: EGR Valve, EGR solenoid, coolant temp sensor, knock sensor, intake air sensor, plugs, plug wires, camshaft position sensor, ignition module, and the PCM computer. With all these electrical parts in my opinion it would be best to have it check by the dealer. This way you are not buying parts you don't need. They will hook it up to an engine analyzer to find the problem.
