Gasoline in my exhaust system - explosion

[Henrikfromdenmark]

I have a problem with my 1977 fuel injected camper. It has only 29.000 miles on the clock, but lately it started to run irregularly and after a while it started to backfire and it was so severe, that the exhaust exploded. I believe somehow that some gasoline gets into the exhaust system, but I can not imagine, why it does. Can it be a malfunction injector or pressure regulator? Or more likely another thing? Please, help/advice needed. Best regards Henrik. Email:

Sounds more like an intermittent spark problem from here. When was the last tune up?, and how old are the plug wires, plugs, and cap and rotor?

Really I don't know. Could be the original one, so maybe 40+ years.

How's your milage? If it's getting worse you could have an injector sticking open. A look at your plugs should tell you if thats the case. But yeah, 40+ year old plug wires can't be helping, that sounds like the place to start.
