Re: jeep 3.7 shooting flames, need advice
Interesting, Jeff!! I wouldn't think that, if the cats. are doing their job, there should be anything behind the cats. (fuel) that would allow combustion to occur. The cats. are suppose to burn any unburned fuel before it gets to the tailpipe.
Oops, I see you deleted the cats. That's why this is happening......unburned fuel being ignited in the tailpipe. Kind of cool looking though....like a top fuel dragster. Do you have a way of monitoring your air/fuel ratios? This can be tough on mufflers, depending on how far back into the system the flame is going.
