During the last couple of weeks my 2004 Venture R/S has been back firing when I slow down, especially if the motor is hot. I have been doing a lot of traveling lately for the PGR and the miles are climbing.
I'm sure some of you have had this experience; is it timing, plugs, or what? Need your help.
PS: Leaving out this morning for Fayetteville, NC for a PGR mission. The mufflers will pop.
