LMG Sputter At Startup - Cold Only Not sure where exactly to put this thread, so I'll start here and see if it gets moved. I have an LMG 5.3 with 123k miles on it that recently started giving me trouble at startup when cold. It'll fire and start, but immediately after it initially fires itll act like like it quit firing and is going to stall. Then it slowly just figures itself out and idles normal. Once it's warmed up, it'll start just normal. Anyone ever come across this before? It's got me scratching my head and I cant seem to find any similar threads.
Another way to describe would be that when starting warm, the RPMs jump up to maybe 2000 and then drop to idle. When it's cold (50F or below outside) and it fires for the first time itll peak at about 1000rpm and then sort of just pause and then stay there. Maybe I'll take a video and post it up.
Thanks in advance.
