Question about 1979 Pontiac Firebird
My 81 trans am with a 305 has a popping sound when I give it gas. When it idles it sounds okay. I don't think its a rod or bearing noise
Change plug wires. If you want to check first, drive it into a garage, or wait til dark, and have somebody brake torque it while you watch under the hood for spark jumping.
