How to increase idle when it is cold?

[zedjr10]

When it is dead cold and freezing outside it idles around 1400 rpm's. I want to increase this to about 1800rpms. How do i do this? FICV am assuming controls this. Or is it something else?

You're talking about the initial idle just after starting? Assuming everything is working correctly otherwise (does idle drop to about 750 when warm?), open the top of the FITV and unscrew the pale yellow piston about 1/2 turn, then put the cover back on. If that is not enough, you can back it out some more.

Yeah everything works ok i just want to increase the cold idle as it takes 15 or more minutes for it to warm up when it cold.

As mentioned above, you can adjust the Fast Idle Thermal Valve to reach your desired cold idle RPM. Make your adjustments in small 1/2 turn increments.

Cleaned out my iacv very well and adjusted my fitv. Idle much better now at about 1800 when cold. Still not a perfect idle. It's a little sluggish trying to start when dead cold but most would say it is working close to perfection.I think i need to clean my throttle body too. That's this weekend maybe.

I Had A Hanes Manual

I use to mess with idle a lot from what i remember the instructions went like this.

1. with the engine off remove the radio or memory fuse from the fuse box under the hood.

2. disconnect iacv (a 2 pin connector on intake manifold somewhere in the center)

3. Locate the idle adjustment on the throttle body in the top center portion. its a flat head. if never tampered with it has like a little sealant over it to prevent it to get loose.

4. start car and adjust to desired rpm.

5. shut engine off reconnect fuse and iacv .

6 start car observe idle.

this is assuming that your fiv and, vacuum lines , and throttle cable adjustments are OK. IF I AM MISSING SOMETHING OR SOMETHING IS WRONG PLEASE CORRECT ME , ITS BEEN A WHILE.

NEXT TIPS ON IDLE FOR F22, H22, AND H23.

The dreaded bogging idle up and down.

1. make sure cooling system is free from air and is topped off.
2. primary suspect on h22 throttle bodies. the fast idle valve is located on the bottom of the throttle body. remove the body and unscrew the gold cap . tighten clockwise the white plastic ring. put back together and wallah.

3. on the f seies intake manifolds the fiv is located on the top right of intake manifold.

He is not having trouble with the idle when warmed up.

The correct way to fix it is to replace the o-ring on the white/yellow piston inside the FITV and the one under the cover, then adjust it as described in earlier posts. Tightening the piston all the way down significantly affects (reduces) the initial idle when cold.

There was also 2 coolant leaks in separate places. That might of had something to do with it also. Not sure that would cause it unless the pressure was really low. Is idling correctly for the most part. Anything above 1800 rpm's just makes it a wierd shift until it warms up. So i think i am keeping the fitv at 1700 rpm's when dead cold(below freezing outside).

So i cleaned the iacv valve and adjusted the fitv. Idle was mostly ok. It still sometimes would slightly be erradic. Then i found a rear exchange radiator hose leak and fixed that. Idle became perfectomento. It was a small to medium leak in the rear hose. I have no ideal the name. Evidently that one i think has more to do with idle than the other major 2 but who knows. Am guessing.
