    How should spark plug wires be removed for the 1987 Chevrolet El Camino, considering the proximity to the Exhaust Manifold? Posted by Bruna S.
    A:
    Mark each spark plug wire with a strip of coded tape (numbered 1-8) before removing them, ensuring to pull on the rubber boot and not the wire itself to avoid mixing up the order. You can Select Your Vehicle to see complete installation and repair tips.
