Until I give it gas and it will eventually smooth out. After a bit, the " Money Light " will come on, throwing a p0300 code it will run fine. I clear the code and start it again with no issues. It is the stumble start that causes trouble code, I can start up when cold and shut off and restart and no stumble and no money light. I can get away with this for a while but if it sits for any amount of time, it starts all over again. It's getting fuel, but I feel like fuel pressure bleeds off. I did fuel pressure test and it held at 50 PSI, but I didn't know specs at time it should be 58 + / - 5 I have thrown all kinds of parts at it, and most of them needed replaced. I believe it's the fuel regulator, does anybody have other ideas on what it could be?
