Today when I got home after a 50 mins drive, I let the car sit idle for a minute or 2. Theres this poping sound coming out from my rear muffer...
"it goes like pummmmmmmm pop pop pummmmmm pop pummmm.."
not loud pops, more like little burps.
pretty irregular and frequent poping....but engine idle quite smooth, just that popping sound from the rear muffler keeps coming up...
somthing wrong? or do I worry too much.
Thanks
