Question about Ford Escort

1 Answer

1989 Ford Escort GT 1.9L HO starts then dies after a few seconds.

My escort starts rough then smooths out to a good idle then after a few seconds goes back to running rough then dies. It has new plugs, wires, rotor, fuel pump( I can hear it) , tfi module is good(had parts store test it). When its running for the few seconds there seems to be no smoke of any color coming out the tallpipe. I dont think its the cat-converter cause i took out the o2 sensor to open up an escape area for exhaust if it were clogged but there was no change in the way it ran. Could it be the fuel pressure regulator or the ecu PLEASE HELP Thanks

    No not a new one but one that was taken from a vehicle that ran good. Can a person test those with a voltmeter?

Check the idle air control valve. This sounds like it is not working right. it controls how much air the engine gets when it is idling. the pcm tells it to open more or close. they get old and dont respond fast enuf.

Good luck

Low idle, engine vibration


I see this is an older question, but in case someone is having the same problem, here goes.
Besides the things above, I'd pull a spark plug, check it. Could just need a tune up, or you could have just a single cracked plug. One bad plug or bad spark cable will cause what you described. I always like to start with the simplest/cheapest solution. A tune up with new cables won't hurt anyway.

The fuel rail does have a service port it is smaller than a tire stem valve but requires a special fitting.pressure should be around 32-36 steady check your power and ground sources to the computer such as ECC relay and the bulb looking ground connector near battery.

If the problem is not a vac leak, it could be the idle circuit inside the carb. You may have to replace or rebuild the carb to fix it.

1997 ford escort idles rough when hot


1997 escort idles rough, the first thing is to make sure the throtlebody plate is clean. This sounds like the idle may be staying to low at times if it smooths out with ac on, when the ac is turnned on the computer raises the idle a touch to make up for the strain on the engine from the ac compressor, clean throtlebody and look at and clean idle air control valve, if this valve is not controlling the idle when needed the engine will idle lower than normal and cause a rough idle.
Another thing is the sparkplug wires, take a look at those, if at night or with a good eye use a spray bottle and spray a mist over the wires and watch for any sparking, this spark may be very small so look at each wire closely or may be big enough to see and hear. this is where i would start. good day.

recheck your cam timing belt, sounds like it jumped on you. PCV valves generally plug into the valve cover and you would have had to seen it when you pulled the head. not all cars have them

Car runs very rough at stops, dies at times but restarts, higher speeds runs great ,smooth. At idle sounds like vaccum leak inside throttlebody also slight manifolds to eng. head air leak, engine shakes...


There is a TSB for the PCV hose. The elbows at both ends get holes in the underside that you can't see unless you remove them and look. This is a very, very common issue on the ZX2. You can get a new PCV hose with both elbows for about $30 from the Ford dealership. You only need to remove the air intake to gain access to the PCV hose to replace it.

99 escort SOHC engine. Idles rough at start up. Smooths out some when it warms up but still idles erratically and surges. Changed the plugs and put new air filter in, but no change. Plugs are fairly black...


If you can find the IAC valve(idle air control) on the throttle body-it should be replaced or try to clean..If you put in new plugs and they turn soot black in a short time period, you have other issues-possible internal engine,such as valve train problems, or a partial exhaust blockage, or the fuel your buying is not good...

1994 ford escort vibrates horribly in idle, does not stall. Idle is set @ 800rpm, runs smooth when raised to about 1200rpm. Suggestions?


Your Idle air control valve is probably going bad. It is located on the throttle body and is a relatively easy fix as it is only held in with 2 screws. Good luck and thanks for using FixYa!
