This makes zero sence. Do you mean your idle doesn't hold steady untill the motor is warm?

Honestly, type better, I can't be any nicer.

So it doesn't hold an idle, how much is it going from is it a slight fluctation example 1200-1500 rpm or is it larger like 1000-2000 etc?

Have you replaced your electronics as of late, dizzy cap rotor spark plugs wires etc?

 

It's most likely your FITV

 

i havnt replace anything lately it idle 2000-2500 could be my iacv bad?

 

check your coolant level and reset the ecu.
and learn to use 4th grade english at least

 

Look at replacing both the fitv and iacv but, more so I think you got it guessing your IACV being dead.

 

i did replace both FITV n IACV use but do i hav to bleed when installed the IACV or it will not werk property? mayb that the reason my engine surge up and down at idle

 

srsly.....



Edit: wtf is up with Max and the amazing changing screen names? lol

If you can't check your spelling....err....coolant level in a car, then you don't need to be driving it.

Turn the bleed screw on the inlet housing on the head out till coolant comes out. Then tighten the screw,then fill the radiator and reservoir up to the recommended levels. Then run the car till its warm with the radiator cap off, top off as necessary, and then put the cap back on.
