Very low idle sometimes tach jumps
I have a 2006 2500 at 213,000+ miles with 4" duel stacks. I have a twister muffler 2' off turbo then off set to a Y pipe then up to the sky. Like a big rig. Sometimes at a dead stop my idle will hover around the 250-300 rpm range. Also the tachometer will jump from there to 1000 rpm and then jitter around In that area. In park or drive makes no difference. I'm not a trouble shooter type of mechanic. I'm more of a If I see it fall off and skip down the road I can put a new one on kind of guy. If someone could point to me in the right direction I sure would appreciate it. Thank you.
