i have skunk2 billet 70mm tb.
it eliminates the fast idle...and everytime i start it up on cold start, it's hard to keep it alive..
i have to help give it a little gas (rev at 1k) to stay alive during that cold start. about a good 1 min then i can let it of gas.
when it's warm up, it has no issue trying to keep it alive.

could it be because of fast idle?
i replaced iacv, 3 ect sensor...

i'm trying to tune my car but i need to fix this first..please help thank

 

do you have a cold idle set in whatever program you are using?

 

well my hondata s300 sets idle at 850rpm.

 

right, but there is more than 1 idle value.
