87 gmc 454 new plugs, wires, cap and rotor. Started fine, idled smooth. Hour later very hard to start. Noticed green wire broken off sensor between two plugs(o2 sensor?) Is this the problem?
no codes showing, fuel pump is functional, not sure of pressure, runs well once started.
have the same problem?
