Since I had to install a 4L80E, and changed over to $0E, I have developed a hot restart issue. I copied the main tables over from my last good $0D tune. Funny thing is I never really got my cold start issue fixed with the $0D tune, now I have just the opposite. With the 0E tune it starts fine cold, after it gets up to operating temp I can shut it off and it will start for a second, then die. It happens real fast. If I ever so slightly touch the gas pedal and try again it will fire right up. I have messed around with some stuff but nothing has seemed to help. The truck is MPFI with a vacuum referenced FPR. I may try removing the vacuum and seeing if it still does it.
