Thumbs down choke?

1995 escort wagon.

Choke idle 1500+ rpm, too high, so when I drive it cold there is a lot of pressure on the brakes ect, dumb ford, also stays on too long in my opinion, finaly, on too often, EG, if I park my fully warmed car for 1-2 hours, when I start it again the choke is on again, is there any way to adjust this thing?
Technology's great if it's used properly, thanks ford.

Start with the links and posts in my signature file below. Possible stuck idle air control valve/dirt in the throttle body.

Yes, the Escort was not "Quality is Job 1" at Ford .

the idle speed for your escort, from cold, is about right at 1500rpm it should drop to about 1100rpm after a few minutes driving and 750 to 850rpm when fully warmed up.thats what my wifes escort does. if it doesn,t there,s something wrong.
you might consider fitting a manual choke kit.
if you live in a cold climate this will effect the times and rpm i,ve mentioned.

You can install a choke kit on a fuel injected vehicle?

no you cant put a manual choke on a fuel injected vehicle but im sure he was probably reffering to alot older model car.
most likely cause is the iac valve as joe stated they commonly stick and idle high after sitting for a short period of time.

This is a fuel injected vehicle. There is no choke. No choke can be put in this vehicle. It could be a dirty idle control valve, but more likely it may be a bad temperature sending unit. It sounds like you have a lazy one. You'll have to be careful which one you replace... there's three!... one for the temp gauge, one for the cooling fan switch, and one for the computer. It's the one for the computer that may be bad.

Recently used a full can of carb cleaner in the throttle body, even though I noticed a sticker on it saying not to clean it? and did a tune-up.
svt, does the choke on your wifes escort also come on as often as mine?
Apart from poor mpg, my car runs ok otherwise, idles fine ect, and I live in a very warm climate, guess Ill get it scanned at autozone, keep you posted.

ejit5729....

Your car doesn't have a choke. SVT is providing false information to you. If your car is a 1995, then it is fuel injected, and NO fuel injected car has a choke.

Kestas and bejay are trying to get you on the right track. Hopefully nothing has been damaged by cleaning the throttle body. The cleaner can eat away at special coatings in the throttle body.

Not this one . But there are early Ford TBI's that DO have a choke. In fact they have a choke pull off and a stat like a carburetor, and excepting for lacking a needle and seat, they are a carburetor in theory. LOL.

However, a manual choke is a silly idea. If the engine is running right, there is no need for a manual choke. In fact, you'd probably screw things up with the manual choke trying to get it right and make it worse. The problem is elsewhere as Cheese and others are alluding to. I agree with them.

From what I can recall, this 1995 Escort should have a 1.8 or a 1.9 liter engine. Both of those are multiport (one injector per cylinder) injected. The throttle body is an air mixing throttle body only.

Additionally, the Escort sold in the UK where SVT lives is not the same as the one sold here. Same crappy name and quality, different car though. Still a bomb no matter how you slice it.

Yes, the throttle body can be damaged by not using the Ford approved cleaner. That is why the sticker is there . The coating helps the throttle body work and not stick.

It's probably a bad IAC valve on the throttle body.

Ahh--Ok, svt....I didn't know you were in the UK. That explains the choke differences. Joe, I forgot about those silly TBI units with the choke. Still, it is an extrremely rare instance where fuel injection is coupled with a choke.

Hey Joe, that sounds familiar, anyway, I have discovered another problem, when I brake to stop at lights for example "decellerate" it takes a good 5-10 secs for the idle to return to normal, could this also be the "IAS" ? There are no check engine lights or such coming on. Thanks man.
