hey everyone. im new here to this forum. i am very glad i found it considering it seems the most informative and members for ford escorts. i found many other ford forums with very few escort topics. anyways glad to be on here and meet everyone.

heres my problem:

i have a 98 ford escort auto 4 door SE model with the SOHC 2.0 liter motor.

recently i have had a problem with the idle on the car. the car starts and runs fine and idles fine but when you give it a little gas just say to rev it up in park or so the rpms go up then takes a few seconds to come back down. its like it lingers up and then takes a few secs then lingers down. i dont have a tach on the car so i dont know the exact rpms but it seems like it revs higher than usual. i want to try to explain it as like a walk away rev where you rev it and it revs and kind of revs a little more than supposed to then idles back down but slower than usual. its very hard to explain and i have looked for threads on multiple boards including this one but noone has this same problem. most are just high idle all the time or rough idle or too low idle or car stalls. mine has nothin to do with that.

another way to explain what happens is that if i shift from park to drive the revs go up for a few secs then comes back down and idles in gear. when i go to drive if i barely tap the gas the car seems to keep accelerating for a few secs more than it should because of the way the revs are going. like if i was to take off in drive and just blipped the throttle the car will somewhat like accelerate itself for a little bit then when the revs start to come down then the engine braking will take over and slow the car down. heres the nitty gritty details on what i have done so far.

i have tried my best to check for vaccuum leaks and i dont see to hear or see any. the cel came on and i had autozone scan it and it was the idle air control valve. these symptoms im having kind of points to it so i bought a duralast brand iac valve from autozone. replaced it and still does the same thing. i took it back and got another one just incase it was bad. installed the 2nd one and same thing. so i took it back also. I have tested it and it seems to be within the correct resistance of 12.5 ohms. it is supposed to be between 6-13 ohms according to autzones troubleshooting. so im thinking that it might be a part that has to be motorcraft maybe? so i ordered one and im going to try it tom. im hoping that fixes it. when you guys have replaced the iac valve on your 98 escorts did you buy the autozones or mototcraft one?

thanks in advance for everyones help im hoping someone has had this same problem and can help me. thanks gagin.

thanks for the link i saw the pic and found where its at but i pulled it out and its just a black plastic piece with the hard plastic hose on it that connects to a rubber hose toward the top of the motor/throttle body. is that the pcv valve? i just pulled it out and it had oil all over it. i though they looked like metal pieces with a right angled elbow coming out of it. is that the valve i pulled out?

sounds like you've found it, I wouldn't go by looks as an indication on if it's working or not, its only like 5-6$ to replace it

the one on my 99 escort was metal I believe.

yea but it is plastic not metal and it has one of the black plastic tubes on it going to the other hose at the top of the throttle body. i cant seem to get this plastic hose off. i think if i just by the new pcv valve i wont get the hose unless i buy the whole assembly. how do i get this hose off to put it on the new pcv valve? thanks again

there are no hose clamps holding the hose onto the pcv?

which setup do you have from the other thread?

rubber hoses connect the pcv on both ends, shouldn't be plastic...

its the second picture in the link. its by the heat shield for the exhaust manifold down below behind the radiator. i pulled it out and its a black plastic piece which i think is the valve and it has a black plastic hose or tube that connects to a rubber hose and that connects to ablack plastic tube and goes to the metal thing on the intake manifold where therea re two heater hoses going to it. i dont have any hose clamps holding the black plastic tube on the pcv. whats your email i can send you a picture of it or so.

ok that's the same setup I had

the long hose on the top part of the pcv that runs up along the valve cover to the other hoses- this lifts out from the bottom part with the pcv connected

there then should be 1 clamp securing the pcv in the hose, the hose around the pcv might be melted so you might have to give it some effort to remove but be careful not to break or crack the hose

i emailed you about this. still a little confused since i dont have any hose clamps securing the black plastic hose to the pcv valve. its just pusehd on there and it looks like the pcv valve has two o-rings or slots where it slips into the black plastic hose to secure itself. its locked in there pretty good. i can twist the hose around teh pcv valve but i cant pull it off. if i pull real hard i think ill break/crack that black plastic hose easily.

the hose that is in the 2nd pic in the other thread you gave me has like a rubber hose that goes all the way from the pcv valve up by the valve cover and to the metal thing on the intake manifold with the two heater hoses. mines not rubber. mine has two separate sections and i have like a 5 inch rubber hose connecting the two plastic hoses and the plastic hose on the bottom is connected to the pcv valve pressed in. no clamps at all. so i dont know if i have something different or since i tgot it used someone changed the pcv valve/hoses and used plastic ones and all but i dont have just a long one piece rubber hose that slips over the pcv and slips on the top of that metal piece at the intake manifold.

PCV on my 1999





Next picture shows the rubber piece the PCV sits in taken off, you can see the metal PCV and the hose clamp i'm talking about, take off the clamp and pull out the pcv.



anyway if you break the hose trying to remove your pcv i'd just bring the hose to an autoparts store and buy a section of heater hose or something to replace/patch it

man you have been so helpful thank you very much for those pics. i went and bought a pcv valve yesterday from atutozone and heater hose for it. i didnt have what you have on the pics you just sent. i didnt have a pcv valve at all. all i had was a black plastic piece that fit in the rubber grommet the pcv valve is supposed to fit in. so i didnt have a pcv valve at all!!!!!! and the black plastic piece that fit in there had that plastic hose that was pressed in. i got to take a pic for you. ill send you a pic later you got to see it. i was pretty pissed when i got it fixed and all it was a 3 dollar pcv valve and 2 ft of hose. somebody didnt put a pcv valve on it and caused my crappy idling. i was so pissed but am relieved now that i fixed it thanks to your help. thanks so much man. i know where to go from now on for any problems. well one more question if you know. i was trying to adjust the headlights cause they are aimed real high and i think you turn this dial that has teeth on it with a level thats on top of the headlight. is that how you adjust the headlights? i need a security torx bit to trun the drivers side but the passenger side you can kind of turn by hand. its a clear dial with white teeth like a circle that has a level in it to tell you if the headlight is level i believe. i turned it and turned it a bunch of times but it made a little difference but not where nit needs to be and the drivers side i cant turn by hand. am i doing this right? lmk thanks man
