Strange New Starting Issue
So, recently over the last couple of weeks when I go out to start up the rig in the morning it stalls out on the first start up. What I mean is when I crank the motor, it starts fine, then drops in revs and sputters out untill it dies. When I restart it it runs fine. Then for the rest of the day, any time I restart it, no problems at all. So for the last week when starting it, I give it a light rev to keep it from stalling and it's fine. All vaccum lines are new, and I'm not getting any trouble codes.
Has any experienced these symptoms before, to find out what the problem was later? It runs and drives fine, just that little issue in the morning. Any ideas? My guess it's a fuel issue, but I could be wrong.
