If your car has an odd miss/occasional backfire;

Get the Chiltons book out, and be SURE, the plug wires are on correctly,

Before you pull the heads off, to have a valve job done. Doh!

.

I had dual exhaust on a 1972 Satellite, in 1977,
and the passenger side had a misfire, and if dark out a flame was visible,
out the passenger side exhaust pipe.

Tried new plugs, new wires, new cap, all replaced One at a time,
so the firing order did not change.

Pulled the heads off, and had a valve job done,
some of the valves were bad; put back together, still had the same problem.

Got the old Chiltons book out, 2 wires on the passengerside of the engine, wires were swapped. {They were like that when I got the car}
