YOUR THROTTLE BODY HEATER ISN'T HOOKED UP HUH? YOU JUST NEED TO REV IT FOR ABOUT A MINUTE AND IT'LL IDLE. COLD STARTS ARE THE HARDEST THINGS FOR ENGINES.

i have the same problem. Throttle body heater? is it an ECU thing or or a coolent diaphram/actuater thingy?

THERE IS A LITTLE TUBE UNDER THE THROTTLE BODY THAT IT CONNECTS TO THE HEAT HOSE, IF ITS PLUGGED THEN IT WON'T HEAT THE AIR GOING INTO THE ENGINE SO IT OVER COMPENSATES WITH FUEL AND TIMING.

My RB25 doesn't want to start when cold. To me it seems that it doesn't idle up like car do at cold starts. This should happen with the idle contorl valve but for some resound it isn't doing it.

Does the AAC hose have to go after the turbo or can it go anywhere after the MAF? Cuz I got mine after the MAF and before turbo and it takes it a sec to hold an idle but once its got its idle its all happy.
