I know where this is going. Not good.
The cases above while can cause backfire, are rare. I said "in 95% of cases"
What is written above are rare cases and not commonly experienced. Any time a car came in with a back fire problem, we always found the problem to be related to ignition.
Fuel on its own cannot cause a backfire, there has to be an ignition source. Most cases that ignition source is a poorly timed spark. Yes, funky valves, cam skipping a tooth, can all cause backfire, but really, how often do you see bad valves and cam timing off? Not very often.
So go ahead and dig up all the cases you want. Yes they "can" cause backfire. As a mechanic, I always go for the most common causes, then if no success, look to the unlikely.
So to summarize, I said in the middle of this thread, what to look for after the OP replaced a bunch of fuel related parts. I suggested to look at ignition as the source of the problem. The OP discovered bad ignition wire. So what more to you want?
I give up. Too many judges without a jury.
