1995 Ford Escort Stalls after warming up

Tonkane · #1 02-17-2005, 07:36 AM

I have a 1995 Escort 1.9L Engine. The car runs fine until it warms up The car just will not idle right once it warms up. The rpms drop off and the car stalls out. As long as your foot stays on the gas the car runs great. If you stop at a light or stop sign I have to slip the car into neutral, with the break on of course, and keep my foot on the gas to keep it from stalling out when the rpms drop.

I have replaced the spark plugs, Spark plug wires, air filter, fuel filter, PCV Valve and filter.

The engine light is not on so no codes to go by.

Any ideas or suggestions would be appreciated. At my wits on trying to figure out whats wrong

Suggestion: Take the car to Autozone to have the computer codes 'read'
It is a free service and they will tell you if you have any emission sensor issues.
From your description, the problem sounds as if it is fuel delivery related, based on the problem becoming apparent only during 'closed loop' operation. However, the computer read-out will give you a starting point.

Autozone will not read the codes unless the Engine Light is on. I was told the engine light would only come on if a sensor triggered it.

Does your engine have the PCV valve located in the top of the valve cover? Is it a Mult-port fuel injection?

The PCV valve is down in front of the Engine block not on top of the valve cover. When you open the hood you look down and can see it. The hose (which is two peices for hose that at are fitted on either end of a bent hard plactic tube) goes from the PCV valve then up to the valve cover. Replaced the end section of the hose where it connects to the valve cover because old hose section came off too easily. My model of Escort Engine 1.9L has a Throttle Body.

As reading, the same thing popped into my head.

Possibly a bad/going fuel pressure regulator on his fuel rail, or fuel filter? Maybe as far as pump or strainer?

There are a couple different configurations of 'Throttle Body' (CFI) engines, and a couple of things that need to be checked:
a. Remove the air cleaner, do not detach vacuum hoses and check to see if they in good shape, not cracked, and not leaking vacuum.
b. Turn the air cleaner up side down and look at the vacuum motor door it should be 'OPEN' If it isn't it may be binding or sticking. Try to move it by hand, lubricate and work it until it moves freely.
c. Start the engine and see if the door moves. If it does, shut off the engine and the door should move within a couple of minutes. If everything looks good. We will move on to the next step.....
The Idle speed control (ISC).

Already replaced the Fuel Filter but will look into the Fuel Pressure Regulator and the Pump and strainer..waiting for a day when it is not snowing out

I got exactly the same problem on my 1995 1.9L escort.

I tried replacing the IAC valve and it didn't help. I also cleaned up the throttle body and IAS bypass and it did nothing. Now, a garageman told me I must replace the wiring, but i'm almost sure it won't work.

Keep me aware if you fix the problem.

I'm also having the same problem on my '01 Escort. Only difference is i have a service engine light on. I'm going to get the light checked tomorrow. Maybe it can give you an idea what to look at.

I would have a shop check the pump pressure to see if it's in spec.
Also the O2 sensor might be a good place to look as when it goes
to closed loop this is computer uses to adjust the fuel injectors.
Also, as previously mentioned check ALL the vacum lines under the
hood as they get brittle over time and can leak. False air will cause
a crappy/no idle every time.

I took my '01 to the dealer with that problem. (have family who works there) On mine it was the IAC valve. I have a temporary used one on there right now. i have to order a new one. Within five minutes mine was running fine. I work about an hour from where i live and i didn't have any problems on the drive.

I was trying to determine if his 1.9L engine was a CFI, and had an air cleaner. The door I was speaking of is in the air cleaner and part of the inlet air temperature control system.
