If it has the notoriously bad Carter BBD carb, you can remove the venturi's and drill them out as they have a tendency to plug up. A webiste that has the blow by blow info on how to perform this is http://rubicon.off-road.com/Jeep/tech/engine/carter.html. It is rather easy to do and will help to keep the venturi's from pluggin ing hte future.
carbs need to be rebiult
you did not say if was carb but if so spray pump in the carb is a good place to start
if u'v opened the idle compensator on top of ur carb check for leak there check the carb seat gasket for cracks and check bottom screws some of them will leak if they're not tight enough
1989 Celebrities are fuel injected, there is no carb.
Dirt in the carb or carb out of adjustment or both.
If it is throtle body equipped, the idle control s solonoid controls it. If it has a carb there is an adjustment screw on the bottom of the carb.
There should be an idle setting on the side of the rochester carb.
May have an idle solenoid on the left side of carb.
1989 Tercel does not have a carburetor, it is Fuel Injected. Wrong. My 1989 Tercel has a carb.
No fuel injection started in 1991. they took the 2.5 from the XJ actually in 1991 that's why it fuel injected. Yours is TBI or carb. The 2.5L should be fuel injected in 1989.
there is a little screw on the back of the carb. if you loosen it, it will idle slower, tighten it, it will idle faster.
On the side of the carb.
fuel injected or carburetor?injected - the idle can be adjusted via a diagnostic computer.carb - you can adjust the idle under the carb very easily.
There are a couple possible reasons. It could be a cracked carb boot that is letting unmetered air into the engine causing a lean condition. It also could be a cracked crank seal causing this problem. Check your plugs to see if it is running lean. Spray carb cleaner onto the carb boots when it is running to see if theres an idle change.
if the air to fuel mixture, or the jets are not correct it will not idle until warmed up or not idle at all. or the choke could have something wrong with it. try cleaning the carb and adjusting the idle screw located on the side of the carburetor and if that isn't the problem then it might need re-jetted
I am having the same problem. Did you figure it out? I think it might be in the air adjustment. I just haven't tried it yet.
there is no choke its got an electric choke on the carb
check the ait. on yhe left side of carb..it control's idle.
Right at the top of the engine you will find the carb immediatley to the right on the carb you will see a flat head screw this will adjust your idle , helps to have a second person on this.
Possible solution, given what facts I have... You might simply need to up your engine idle speed. If it has a carb, then it will most likely be accomplished by screwing your throttle set screw in or out where your throttle links to the carb. Adjusted correctly, your engine will usually idle higher in Neutral than in Drive. I don't know how severe your problem is, but this may fix your problem. Be smart. Be careful.

If you are getting gas into the float bowl, I would say your jets are clogged. Take the carb off, pull the idle and main jet out, soak them and blow them out with air. Make sure you can blow through them before reinstalling them in the carb. This should solve your problem.
twist the screw under the carb
adjustment screw is between throttlre linkage and carb body on the right side of the carb as you stand at the front of the car looking at the carb
unit has had fuel sitting in it, carb is plugged, fuel lines probably rotted, fuel filter hardened. always use fuel stabilizers, this will prevent it from happening, but it is for sure a carb problem.
adjust your idle screw on the side of the carb its the one with the spring on it. if that doesnt help then take the carb apart and clean it to make sure theres no dirt in it.
