72cut Posted October 30, 2022 Share Posted October 30, 2022 So just started my 88 in order to move it, was idling pretty high. I heard what is best described as a backfire didn't think anything of it. When I went to back of vehicle i saw large amount of soot/carbon under the tailpipe as well as spread out across my garage floor about 4-5 feet. Truck seemed to not idle as high. Cause? Good thing? Bad thing? Neither? Thanks Link to comment Share on other sites More sharing options...
Eagle Posted October 30, 2022 Share Posted October 30, 2022 Could have been a mouse nest in the tailpipe. Link to comment Share on other sites More sharing options...

pizzaman09 Posted November 3, 2022 Share Posted November 3, 2022 Mine will backfire every once in a while if I am running it hard and change gear after being up over 4-4.5k rpm. Link to comment Share on other sites More sharing options...
