Last fall I purchased a 1969 Sedan Deville. 110k one owner. The only thing that is not original is the electronic ignition. It has a Napa "brain" that looks like the Chrysler one in my Dodge.
Here's what happens: It starts easily, and runs smoothly. For about 20 minutes, then it will cough,sputter and finally backfire so hard to litterally blows the seams apart on the muffler. The first time I thought it was just a fluke. So on goes a new muffler. I'm on my third muffler and getting very tired of this. :mad:
The timing is set correctly; new plugs,wires,cap and rotor, fuel filter and coil. Can the pick up module in the dist go bad? I wish it still had points! It came from the factory that way; good enough for me!
Also, it has 2 ballust resistors. One at the coil and one on the firewall. This too seems strange.
Any ideas? :confused:
