Hey guys! I have noticed on cold start ups like 50-60 degrees that my truck has like an erratic start up then smooths out. I have been using rev-x fuel additive for 1000+k miles now and now i've been smelling a fireworks smell "sulfur" once its started, It only lasts 5-10 seconds, NO SMOKE, Enough to stink up the cab for a few mins. All my numbers look ok, FICM 47.5-48v cranking, run syn 5-40w rotella with rev-x, also tuned on IDP xtreme street, Anyone have any ideas? Thanks!

My vehicles always smell like fireworks.. But that because I put on public fireworks displays.

50-60 degrees.......I'll let you know once winter hits!!!! I'm running the same tune and oil, but have never smelled anything that resembles fireworks in the 6 or so years of having this thing.
