So lately my truck has been surging a little bit. Usually does it when I come to a stop or if I let it idle for a while. I use diesel Kleen every fill up. I've heard that running ATF in the fuel will help this issue. Just changed the fuel filter last week. It's not surging bad as in the RPMS drop, but just enough to be noticeable. Anyone run ATF in their LB7? Thanks for any input
