Exclamation 93 ford escort 1.9, big problems...

1993 Ford Escort 1.9l Automatic 2dr Hatchback

Last thursday my car wouldnt start almost out of no where and came close to getting stranded but i got the car running. When it finally started i noticed something different, the whole car was shaking, the acceleration was gone and if I let it idle to long it would die on me.

So i took it in and had two of the three motor mounts replaced whiched helped with a slightly noticable amount of the shaking but nothing with the acceleration. So I replaced all the spark plugs and cables, made no difference but i realilized something when I was doing trouble shooting that when I removed one of the cables from the spark plug and started the engine, then put it back on (the engine still running) it made no difference. I tried with the other cables and it made a difference on everyone but that one. so I unscrewed the spark plug and put the cable on it, stated the car and the spark plug was sparking.

I think it might be one of the fuel injectors but I dont know how likely that would be. i was also told by the mechanic that two of the cylinders were not operating. I replaced the air mass flow sensor, and the vaccuum hoses within the last year. Any ideas it would be greatly appreciated.

I was just told it was either the intake manifold gasket, the computer or one of the fuel injectors, what is most likely?

I was thinking coil pack, but you said it was sparking. I would check for compression and smell in there to see if you are getting fuel. What condition was the spark plug in when you took it out? like new? white? wet? glazed over?

Start at the top
Pull the codes

You can DIY it with a voltmeter
http://www.troublecodes.net/Ford/

The EEC-IV computer that controls your engine can store many trouble codes w/o throwing the Check Engine Light

You also would want the Engine Running codes too (KOER Codes)

Even if it come up with all "pass" codes, that tells us something, and where to look next

When i pulled out the spark plug it was brand new, the old one was pretty worn but only that one, it was wet though, and we lit it with a lighter to see if it was fuel but it didnt catch on fire. I will check the trouble codes.

The trouble codes are 643 (Torque Converter Clutch Circuit Failure
) and 57 (Transaxle Neutral Position Switch Circuit Failed Open
)

Sounds bad, like a trany problem....

It does have a problem accelerating, and has a really hard time going fast than 45, but its idoling rough and the cylinder seems to not be firing. I ran the trouble codes with the car running and got a 538 (Insufficient RPM Change During KOER Dynamic Response Test) and a 536 (Brake On/Off Circuit Failure/Not Actuated During KOER)

dont worry about codes its a four cylinder running on 3 cylinders its not going to have any power or run very smooth until you get it running on all 4 suggest a compression test on all 4 cylinders, you can check the intake gasket by spraying carb cleaner along the gasket while idling if you notice any change in the way the engine runs then it could be an intake gasket leaking just use a small amount of carb cleaner and have a fire extinguisher handy if you are doing this yourself.
if the above 2 items dont show nothing wrong then you can check for injector pulse at the injector and do another spark test this time using a spark tester or making one out of an old spark plug and gapping it at about 3/8 of an inch to check the coil.

Maybe you just blew a head gasket and the wet plug was antifreeze.

Any signs of a blown head gasket?

Head gaskets can blow in all sorts of ways and create different symptoms. Sometimes they blow between the cylinders causing compression loss in adjacent cylinders. You said the mechanic said you had that. Sometimes head gaskets blow and let exhaust gas into the water (some mechanics have a test gauge that goes on the radiator to test for this). Sometimes oil and water intermingle, more heavily one way or the other.


You said you have "no compression". What is the reading exactly on all the cylinders. You really need to check and record this.

If you have sever loss on adjacent two cylinders, you ain't selling that car for much the way it is anyway. If you were game, you could tear the top off and have a look. Any way you slice it...low/no compression on two cylinders only means something sever internally is amiss, and the place to start is at the head(s). Any other kind of leak, including manifold gaskets, are not going to affect the compression. Low/no reading (in only one or a couple cylinders only) can be caused by: Poor seating of the compression gauge itself (but if you are getting repeated good readings at other cylinders and only get bad ones on those two, you can rule that out), bad valve, bad head gasket in that area, bad rings, burned piston.

Had this problem on same car.Pieces broke off the # 4 cylinder valve and but hole in piston. Check compression.
