    Check your air intake hose from the filter to the intake manifold, especially after the MAF sensor, what is the fuel pressure?

I would check and clean the MAF sensor, check fuel pressure, and check fuel pressure regulator. be sure to run fuel pressure test with the regulator hook up and disconnected, if pressure is low cahnge fuel filter and retest, if still low may need to replace fuel pump. Also check the injectors to see that they spray a full cone of fuel. Hope this helps, let me know.

    "moparownr,"
    Am (or *think* I am) having the same problem. (But have no idea what he means by "Trouble Code 172." His car "talks" to him? :-)
    I was on the way back from an hour and a half trip thru the hot, dusty, NM desert (I spoil my '94 Escort. She's used to the cool, pristine air of the mtns...), on a mid-90 degree temperature day, continuing to push the 65 mph speed limit most of the way when, having almost crested a not-unusually-steep mountain, my car began to lose power.
    It felt like I had (accidentally) *gently* pressed the brake pedal, so I lifted my foot, checked to be sure I was on the accelerator and pressed the pedal. It sped up; I thought all was well, but I never got back up to speed, even going *down*hill. (I was still in gear, of course.)
    I put it in neutral so as not to be stuck w/out the safety of the shoulder, and when I got to the bottom, tried putting it in gear again. All the panel lights came on, complete with "CHECK ENGINE" light and she died. (Temp guage in the low normal range; fluids all fine....) I tried an immediate start -- no go.
    Had the same "feeling" as when I'd triggered the "Fuel Cutoff Switch" so I despite *knowing* I hadn't, I got out, popped the trunk and checked it. Also fine.
    So, for want of anything *else* to do... I smoked a cigarette and waited a bit. (My solution of second to last resort.)
    About 9 minutes later (the time it takes for a cig) I tried to start it again. It starts, no problem.
    I'm back on the road, get to about 40 mph when the car begins slowing again. I pump the accelerator, it seems to gain a little power, then slows, panel lights come on w/ the "CHECK ENGINE" light and it dies again....
    I had a travel-companion that day. A friend was following behind me (coz for *some* reason I'd asked him to do so, despite knowing his "slower than molasses" driving habits drove me nutso!)
    The first time it happened, I'd told him what was going on and he *immediately*, no hesitation whatsoever, said my fuel filter need replacing

Understanding Trouble Codes 111, 211, 172 Hey everyone,

recently pulled some trouble codes from my ECU, the KOEO code gives me 111, which the book says is a system pass, so I am assuming thats not a bad thing. I further went on to get the stored codes which are as follows (I get the same codes while doing a running test as well).

1996 ford escort, p0171 code and replaced all vacuum lines,. bad injector maybe? one ticks louder than the others. i cant find anything wrong


Hello, Its possible the noisy injectory is a problem. The code p0171 is a lean code. This usually means there is a Vacuum leak allowing more air into the engine than fuel. You can take a spray bottle of water and mist the engine while it is running. When you come across the part that is allowing more air into the engine, there should be a RPM change. Fix the part you find.

Usually the p0171 Code is an average of all cylinders on 1 bank of the engine. You could easily have a clogged Injector making the fuel mix lean. There are some kits in which you attach a tank of cleaner to the fuelrail and run the engine on the cleaner until it stalls. You will need to ask an Autoparts store if the kit is available.

In any case, reset the trouble light after making a repair.

What does the trouble code PO171B mean on a Ford Escort ZX2


P0171 is O2 sensor indicates lean. You probably have a vacuum leak. The most likely and common cause is the PCV elbow at the front of the engine.

Trouble code 172 ford escort


system to rich(bank 1). Clean the MAF with QD electronics cleaner and see if it fixes the problem. Otherwise, you might need to replace the 1st o2 sensor and/or the maf. bank 1 is the bank where #1 cylinder is. also check all vacuum lines. if cleaning maf sensor does not help, then replace front 02 sensor on bank 1. the one before converter.

Battery is draining and car isn't starting


172. (R,M). Oxygen sensor not switching - system is or was lean - Single, Right or Rear HO2S - Fuel control .... 583. (M). Fuel pump current was excessive - Power / Fuel Pump Circuits ..niether one of these issues would prevent the engine from turning over, but if one came into the shop not cranking, look at the batery, jump it to eliminate it as a possiblity, and then turn to the starter

I have two fault codes 00172 and 00111 what do


the 172 is saying the system was or is lean, the 111 cose is a system pass code meaning nothing is wrong, your test cycle ends with this code meaning no more codes present. As for the 172 code, check your intake tube between the air filter and the manifold for cracks/leaks, also check for any other vacuum leaks. Clear codes by disconnecting the battery positive cable for at least 10 seconds. Hope this helps, let me know.

yes an o2 sensor can cause the mixture to go lean or rich. But you have another culprit also a knock sensor can cause this also. for the miss this is more of what the knock sensor would control. Hope this helps you
