Thread: Cold idle wayy too high..?? please help

hey guys i just threw in a ve in to my b13 i timed it to 19 degrees running 93 oct (i hope this is safe im new to ve's) and when she is warm its perfect right under 1k rpm is where it idles at... the problem is on a cold start it idles all the way up to 2.8k and stays there the other ve that was in there b4 it blew up never did that what could the issue be any ideas appreciated here are a few things it has 255 walbro f/p, jwt ve ecu im pretty sure it has a n60 maf im running the ve injectors and i have a nismo f/p regulator but now im using the stock one

oh yeah and another question i forgot.. the connector on the end of the knock sensor broke when the old motor was pulled out does the knock sensor connect to the clip thats on the same harness section of the injectors right on the end of #1 ?? this is a b13 harness thanks for reading i will appreciate some help i just don't have the time to go thru all the threads work and school are killing me

should i tweek iacv wen i frist start it up in the morning?

couldn't find anything with the search button? try VE cold start.

not sure why, but soo many ve's seem to have idle issues.. some people are lucky, or just smart an dont have issues.. pretty sure my iacv is toast.. i partially use the TB screw to aid my idle.. once warm its purrfect! lol but shes a pain when cold..

my idle is low when its cold.....ha!

i have to baby sit my throttle an hold it where i want it for a few mins before it'll stay, other wise it'll try idling at like 5-600 or even just stall.. its kind of a pain in the but, but not as much of a pain as stalling at stop signs an stop lights all the time.. or idling at like 2000 rpms.. lol

for real yo ..all these lil parts can be a pain but i used the TB off my old ve and she idling like a kitty now no more baby sitting in cold mornings with the hood open and a screw driver =)

is it cause we're using de tb that were getting high 2k cold idle?

other way around. High cold idle, VE Tb, mechanical adjustment. DE tb doesn't have that feature.
