update on LT1 cold start/idle issue

so you might remember my post a week or 2 ago about how sometimes my car will run for a half second and then die on initial startup and then run fine on restart.

i had also mentioned sometimes it would start up but idle rough. well i caught that on video today and something suprising as well.

normally when this happens i will shut the car off and restart it to clear the problem however today i was filming and was letting the car run. after approx 45 seconds the car actually started running normally. you can hear it on the video. weird to say the least.

does this mean it's more likely something like an IAC problem than the fuel pump/FPR i was originally suspecting?
