Hick-ups during initial few mins of warming 280z

[MH77280Z]

Hi Guys,

My car has been running fine for the last over a year since I cleaned all the fuel lines and gas tank etc. New fuel filter also at that time. Recently there was a leak in one of the small fuel injection hoses on the fuel rail. I replaced it with new hoses (2 of them).

Now when I start the car it cranks up fine but after few mins it seems it is starving on gas and tries to pull back and sometimes die if I dont keep the RPM at 2K with a little throttle. Once it warms up close to normal engine temp it can idle normally and I have driven it well over 50 miles at 70mph and no issues. Any idea whats going on?

Sounds like the AAR is closing too soon.
