Default Re: '87 2.5 4 cyl backfire

I had a similar problem with my SC3800 (also has a DIS ignition), in my
case is turned out to be a flaky ign module. It would accelerate fine
when cold but as soon as it warmed up I could cruise at speed but if I
accelerated too quickly it would miss and backfire.
