I just bought a newly built 1998 wrangler with (with 5.7L V8) but I'm sad to report it's been consistently stalling when I turn out of a stop sign after a cold start in the morning. It runs perfectly great when warmed up so I've isolated the issue to a cold start. It originally had a FiTech go EFI system on it and just swapped it out with a Holley Sniper 511K system in effort to fix the stalling issue.

Unfortunately, after my first run with the new system this morning I'm experience the exact same stalling issue. I also sometimes hear a loud screech when I turn on the ignitiion in the morning. Any help, guidance, or suggestions would be greatly appreciated. I've taken it to 3 different shops yet can't find anybody that can help me!
