Car stalling after first start in mornings

[Mkeating8]

Just had remap done and ever since my Car stalls when engine is cold. No power in acceleration and car jerks for a couple of seconds. This goes away straight away and the car is fine then. No check engine lights appear or no codes. Any ideas on fix?

Simple fix may be low pressure fuel sensor which is cheap and easy. Unfortunately for me I had the same problem with misfire/shaky idle at the end of the cold start sequence and it ended up being the secondary air check valves at the back of the engine, which cost me 2k in labor. Mine did this for a while but eventually threw a code for bank 1 secondary air valve stuck closed and that's when I had those replaced.
