Rough Idle and dying when cold?

I have a 97 stroke and am having trouble since it has been cold. It will usually start and idle normally for 10 seconds and then start to idle roughly for about 5 seconds then it will die. If i try again and give it a bit of gas it may idle without dying. If it warms up after about 4-5 minutes of forced idling it will switch to normal idle and then it is fine and everything is normal. I don't want to run it when the idle is rough so I havn't drove it in awhile. I have changed the fuel filter and added a anti gel additive, and it didn't make a difference. Any help would be greatly appreciated.

Thanks for the reply. no i have not, but after reading a few threads I thought that changing the cps may be recommended. Ill go ahead and do that. Are there any other ideas to consider?

unplug the ebpv and it will be fine, if you look near the turbo there is a wired connection, just unplug it there, the next time you start it cold, it will be much bettter. also try plugging in the block heather when it gets real cold.

mine used to do the same exacpt thing,

Thanks alot. That seemed to do it. I unplugged it, it started and ran great. Do I need to plug it back in, or leave it unplugged, or unplug it to get it to start, and then plug it back in? Your help is much appreciated.

no you can leave it unplugged. it is supposed to help speed up the warm up. just let it warm up for a few minutes before heading out

i'll probably invest in a high idle controller
