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.
