Hello all! I am new to this forum and I am so glad I stumbled upon it. I have not worked on a lot of vehicles, but I am learning and wanting to. I have an 83 El Camino with a 305 and recently it began to sound like it is suffocating in a way when I drive it. I have changed the fuel filter and cleaned the carburetor. I don't think its the fuel pump because I couldn't do anything. It runs, just sometimes I feel a lag in it. I undersand these are descriptive terms and may not do a lot of good in describing what is actually going on. But I figured it was worth a shot. Thanks for your help! Its just that I would rather try and learn it for myself than give up and take it to a mechanic. These engines are a lot easier to work on compared to the new stuff.
