Check Engine Light

This guide will help you get the codes

Come back with codes and will see what we can do.

Not sure what the cost would be I can estimate about 1 hr labor @$90 plus $75 coil.
You have three coils each coil fires two plugs. Why they go down? There electronic they do what they do. Heat from engine, vibration, firing thousands a minute, 79K miles and @8yrs. Service would be a few reasons. So can't speculate on the other two.
Good luck

Most likely it will
if PCM see all OK and no more misfire 50 or so drive cycle and not key cycle
my suggestion is that it may need a tune up and or weak coil
you can reset the codes and PCM by disconnecting the battery if no OBD2 scanner available

Hi there,

You may have a vacuum leak around the IAC or the IAC motor is faulty.

Is it idling roughly? If so, I suggest either cleaning the IAC, or replacing it entirely.

Lets start with what is the exact code numbers you have not code descriptions?

Sounds like the guy replacing the coil is guessing the computer is a expensive guess. Is he willing to pay for the computer if it doesnt fix it?Without testing some Thing's cant tell you whats going on does the coil spark when it runs poorly?

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

Go to Autozone or Advance Auto and get scanned free-

Or how about paying for the coil thats not the issue?

I've been thru the bad ignition coil thing with my wife's '03 escape.....wanna read more of that, here's that story......i had absolutely no codes show up after scanning it on several different occasions with different scanners

........or you can skip down below this and read about the "stalling issue" i had before the skipping issue

this was an issue with her's that i worked on hither and yon, for months

i promised myself, i would figure out the cyber controlled critter without the help of a "pay mechanic".......technology has went overboard...i'll keep my 2 jeeps that are 36 and 67 years young

reckon my symptoms are sorta the same as yours?

i had input from here also....ended differently

disregard all of this, if we're not on the same country road

thought i'd sling it out there, for observation anyway....open for any questions with mine....hope it's simpler than mine!

i went thru same deal w/ '03 ford escape 3.0 v-6

repetitive, fast hesitations (stumbles), lasting 1-2 seconds, varied in how far the "sets" were apart, it was more evident climbing a incline, while slowly administering gas....random or none on level ground......every now and again at idle, but very seldom.

---no codes/ no cel --- (cleaned 1st, and/ or replaced the following

new plugs............then "genuine plugs".....bah-hum-bug!!!, nothing wrong with the other new ones, i just installed!

boots and springs

air filter

maf

egr

a new iac for sheets & giggles! ....prevent-maint...if for nothing else!

performed mega vacuum leak searches several times.

fought with wife many times over situation, 2+ months!

i really hated taking off the "plenum" so many times to access the other 3 cylinders.......my old jeeps are so much ezer to tinker with

each part seem to fix it for a day or two....i did not mind replacing the suggested parts, as i am all for "pm" and she's got 100,000 miles on her rig.

the final cure was #3 misfiring (lucked into the correct cylinder) my mission was gonna be to swap a new coil pack down the line, till it stopped

#3 was the ticket!

i had tried to get the technical school to ride me with their portable machine---things did not work out, with their schedule.

i went to a salvage yard to get a used pack ($10) to swap around to figure out which was bad, then buy a new one, if the "donor pack" solved the problem.

so happened, the salvage yard guy had a machine, he found a stored code, it said #3 had misfired.....my little code scanner could not tell me that, or the others i tried!.....i think his was a "snap on"

runs perfect now, with the new $79 coil pack!

if it had not been for the stored code, i was gonna "one at a time" swap the coil w/ the 1st ez 3 to find the misfiring one......if it happened to be one under the "plastic plenum"

the tentative overall plan was to take off and replace the plenum one time only!!!---but swap the "3 good" front coil packs to the rear.....then "test" the 3 ez front ones (relocated from rear) one at a time with the "donor coil pack"

the stored code made it ez on me, locating the bad pack

.......and yes, "a124" still works, i just checked

keep us posted on progress

Check and test the TPS and MAF sensor
