my setup:

b16a
skunk2 intake
super90 trottle 70mm


my prob:
when engine
cold condition,the idling about 800rpm
hot condition,the idling about 1500rpm

hot mean when i let the engine running long time or when i driving anywhere.

if i adjust lower at the trottle side...when cold time want to start my engine its very hard...need to push accelerate pedal a bit then can start.

any advise?

 

Im betting your fitv is stuck or the aicv has gone bad. Either one could cause this problem. You prolly have your idle set to 1500rpm and it drops to 800rpm when its cold because of no lube.

 

with super90 trottle i no more use fitv.....the iacv i also already change it....but still same

 

i dont know anything about super90 how does it regulate the fast idle? if it just bypasses the fitv and its been like that since the super90 that normal i guess.

 

problem solved....after did my adjust tap pad and tighten my timing belt....
