Question about 1997 Ford Escort

1 Answer

Low power under acceleration on 1997 Escort

I have a 1997 Escort with 2.0l. 145k miles on it. it idles fine but, when you accelerate it has no power. It does not miss or smoke it just has no power. I thought it had to much crank case pressure so, we knocked the guts out of the cat converter thinking it was plugged but, did not help. I changed the fuel filter but, no difference. I pulled a vaccuum on the EGR valve and the engine died so, it seems to be working. I cleaned the sensors on the air flow sensor but, did not get any dirt off of them. The plugs and wires were changed about 3 months ago. I checked the fuel pressure and it is 34 lbs at idle and 40 lbs when reved. I am at a loss for now. I have owned 9 Escorts and this the first one to ever give me problems.

    Do a compression test. Your compression should not be less than 100psi on any cylinder. Usually the symptoms you describe are because the cylinder head is bad. Your cylinder head is made of cast aluminum, and the valve seats often break away and cause power loss, and engine damage if not corrected. I've personally seen this issue over 20 times on escorts.

Check the harmonic balancer. it is probably bad and its causing your timing to be off. if its cracked or wobbles replace it. if not the woodruff key might be twistid and causing the problem. id pull off the harmonic balancer and while you have it off check the timing belt. if the timing marks dont' line up replace the belt and water pump. its recommended to change the belt every 60,000 miles. if the belt is good replace the balancer.

SOURCE: I have a 1995 E350, 5.8, 130k miles. Always well

Maybe the timing is off, could ir be that you accidently moved the distributor while replacing the cap and rotor? If you have acces to a timing light give it a try. Good Luck.

My 97 ford escort runs fine on 0 solpe roadr. but when I drive uphill it hesitated on acceleration.


It sounds like low fuel pressure to me. Possibly caused by a clogged fuel filter or a weak fuel pump (or both). I would try changing the fuel filter first.

I am having the same issue on Mitsubishi Galant 02. Clattering on acceleration, herky jerky idle. Pulled a code multiple cylinder misfire. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. I do however know my fuel injectors do need cleaning, he hasn't ruled that out either. Have you pulled any code on it? I have read on engine knock sensor going out on some of these also. Hope this helps some.

Can you tell the location of the idle speed valve on a 1998 escort gti please


You will find idle speed controllers in the area of the throttle plates. In order to work, air must bypass the throttle plates.

Have you changed your oil? Rotella 15W-40. These engines really don't like old oil. It becomes too thick for the injection pump to work correctly. Another possibility is a bad cam sensor on the front of the motor. Most engines call this the crank sensor but on this engine you have to look it up as a cam sensor.
