Hi All,

My Ford Escort 97 has developed a new fault :roll: Since last Couple of days, Engine is cutting off while driving specially while approaching traffic lights, corners. Engine Stalls & the battery & Oil Lights comes ON . I managed now two occassion being alert & immediately starting the engine while car was in motion.

It's a Zetec - 16 valves engine.

What could be the probable causes ???
Kindly help at the soonest possible.

Thanks in advance.

While the clutch is depressed?

The oil and battery lights come on because your oil pump and alternator stop turning. That's normal when the engine dies. We just have to figure out why your car is stalling while (i'm guessing) it's coming down from revs to idle.
If you get a chance, run by Advance/AutoZone/NAPA and have your codes read.

Yes. The Clutch is depressed. The Battery light flickers sometimes while driving.

I went thru the Haynes manual. It asks to Clean the Idle Control valve & Air Throttle body with a carb cleaner. I am unable to locate the Idle Control valve. Where is it :roll: Further what can go wrong with the Idle Control except carbon deposits??

Except this problem, it absolutely fine. Hope to get an answer soon.

When your engine cuts out, is the throttle completely shut?

Try this:
1. Roll to a stop with the clutch in and the throttle closed (foot off the gas completely)
2. Roll to a stop with the clutch in and throttle partially open) slight pressure on gas pedal

Does your car hold an idle WHILE WARMED UP? There are two bypass valves in your car... one which is not electronically controlled, known as the bypass air valve (it operates by a bimetallic coil that will shut when the operating temperature is reached) and there is also the IAC, or idle air control valve, which is electronically controlled by the ECU. If the car is cold, then the problems of the IAC will not be apparent because the bypass air valve is essentially doing the work (hence high idles on cold cars). But when the car is warmed up, the bypass air valve should be shut and then the IAC flaws will become apparent.

So warm up the car fully, then put it in neutral and see if it holds its idle. If it doesn't it's most likely a faulty IAC. The IAC is located on the underbelly of the throttle, just beneath the plate. It should look like a little black box.

It may be your IAC, but the statement about the battery light flickering makes me think that it's simply a bad connection to the terminals.

Before you do anything else, take both clamps off the terminals of your battery and clean them thoroughly. Even though the clamps may be tight doesn't mean they have a good connection.

Also, when the car dies, does it hesitate at all, then die? Or does it just flatout die?

Thanks Seragn for the detailed reply. As per your suggestion , I tried the few checks & observed as follows.

1) The Engine Shuts when the throttle is completely off. Clutch Depressed & 1/4th to brake while in 4th or 5th gear.

2) It's alright at idle, no dropping of rev, either with Clutch depressed or not.

3) The Engine Shuts off while driving without any hisstation, no jerks. I know only when I try to put acceleration & It won't accelerate. It dies very smooth.

4) I Checked & tightened the battery terminals. No loose connection, no corrosion.

I now started feeling as if it might be clutch which is at fault. It happened twice when I was in 5th gear & applied clutch a little fast. Anyway that should not affect the Engine Running.

Could there be a problem with the clutch??

I look forward to suggestions :idea:

I'm sorry if I don't completely understand what you're saying, but are you saying that the engine dies when you push in the clutch?

Generally speaking, if the engine is dying when you step on the gas, it's usually a problem with the VAM or a vacuum leak.

Have you checked the diagnostic for a thrown code?

Clutch probably isn't the culprit.. and by probably I mean, not unless your tranmission is seizing up... which you'd notice.

While sitting at idle, pump the brake pedal and see if the car dies.

Have you had the codes read yet? I can almost guarantee you it's an electrical problem since "the battery light flickers while driving"
