89 Ford Escort problem

[snowfighter]

1989 escord have new sencors, plugs,wires,rotor, cap,fuel pressure regulator,electric fuel pump,fuel filter, when the temp. gets down in the 20s, nine times out of ten it won't idli?, stalls and starts right back up, will do this until the engine is warm then it runs fine Anyone have anything else I may try?

It should go into a high idle and fuel should be richened till the engine warms.

I'm not familiar with that engine, does it have a carb, throttle body or injected? A manual would save you a lot of trouble shooting and save you $ on unneeded parts

[snowfighter]

Surface it has the throttle body with the mini-injector on top of the body, mechanic checked the catilatic coverter and the emission valve, also cleaned the throttle body and set the idle.

Have you tried having it hooked up to an OBD scan-tool yet? Auto Value offers free hookup and diagnostic. That may at least give you an idea on where to go from here.

[snowfighter]

Had a local mechanic work on it, he said 89 computors were not as high tec as now days and you have to do alot of cross jumping when you hook up to this one?Have had a 84 escort years back that had trouble with moisture and was recomended about a vented distributer cap? Have you heard of anything like this. I know frosty morning seem worst.

[Steve Bakken]

Sure can't hurt to try it.

Try replacing your idle air control valve.Mine would start up fine run for a little bit then start reving up and down like you were in side stepping on and off the accelerator.

It should be right on top of the motor, a small dome shaped part with a plug in to it.Payed $30 for my last one.

I'll try the control valve it sounds something like my problem because it will idle up and down and some times catch its shelf and keep going or sometimes it just stops like you shut the key off but will start right back up

[Surface Tension]

Thats were is was going to. Give Benny a star, I think he hit the nail on the head. Let us know what the out come is.

[snowfighter]

Benny Feel I'm fairly mechanical inclined but can you discribe the air control valve alittle more detailed. I looked today and theres a plastic domed about 2 inches square with a wire plugged into it and a vaccum hole on the bottom, mounted along side the carb on the intake manifold on the drivers side.You wouldn't mean the dome on the top of the carb(throttle body)under the air cleaner which I thought was the fuel pressure control. Priced the idle air control valve at bumper to bumper this morning 82.00 plus tax

[snowfighter]

Benny figure out where the idle control valve is local mechanic said to take apart and spray with carb cleaner, so will try that first before I buy new one, let you know what happens.
