WIFEY HAS A 2003 FORD ESCAPE W/ A 3.0L

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 36 AND 67 YEARS YOUNG

Reckon my symptoms are sorta the same as yours?

I had input from a few of the guys here also....my fix ended differently than what was suggested

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

THIS WAS THE SYMPTOMS THAT MY WIFE'S ESCAPE HAD!

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 these parts 1st, and/ or replaced the following:

New Plugs............then "genuine plugs" (2 new sets).....Bah-Hum-bug!!!, nothing wrong with the 1st new ones, I just installed!

Boots and springs on the bottom of the coil packs---all

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!..............and she wanted to take it somewhere....other than me

I really hated taking off the "Plenum" so many times to access the other 3 cylinders.......on the Escape, it's like a rack of ribs curling over and covering the back side of the engine

Each part I thru at it seemed 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) I was gonna 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 with 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 much better scanner, he found a stored code, it said #3 had misfired.....My little code scanner could not tell me that!.....I think his was a "Snap On"

Runs perfect now, with the New $79 Coil Pack!...........WHA--HOOOOOO!!!!!

IF IT HAD NOT BEEN FOR THE STORED CODE BEING FOUND, I WAS GONNA "ONE AT A TIME" SWAP THE COIL W/ THE 1ST EZ 3 UP FRONT (THIS IS A SIDEWAYS ENGINE) TO FIND THE MISFIRING ONE......IF IT HAPPENED TO BE ONE UNDER THE "PLASTIC PLENUM"

THE 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 (NOW RELOCATED FROM REAR 3, AGAIN HIDDEN BY THE PLENUM) ONE AT A TIME WITH THE "DONOR COIL PACK"

THE STORED CODE MADE IT EZ ON ME, LOCATING THE BAD PACK........BUT I HAD A PLAN, JUST SO THAT DANG PLENUM ONLY CAME OFF ONE LAST TIME!

MAMA IS HAPPY NOW!!!!!............I'M GLAD I AIN'T BOTHERED WITH IT ANY MORE.......IT WILL BE PAID FOR THIS MONTH, CAN'T WAIT TO SEE WHAT KINDA BREAKDOWN IT WILL "ANNIVERSARY" ME WITH AFTER THESE 4 YEARS OF DOING PRETTY GOOD

I DID NOT HAVE ENOUGH INFO ABOUT YOUR RIG (ENGINE SIZE--OTHER NOMENCLATURE) TO SEE HOW MUCH A NEW COIL PACK IS FOR YOUR TRUCK

SHOULD YOU NEED A COIL PACKIF ADVANCE AUTO PARTS IS A STORE AVAILABLE TO YOU.......PROMO CODE "A124"......WORKED YESTERDAY AND WILL SAVE YOU THE MOST MONEY

IF AAP IS NOT AVAILABLE TO YOU---DO THE PROMO CODE HOMEWORK TO MAKE IT WORK "SIMILAR" FOR A STORE IN YOUR AREA

HERE'S THE LINK TO SHOW YOU WHAT I DO/ HOW IT WORKS FOR "AAP"

DOES MY SYMPTOMS SOUND LIKE YOURS?

THE MEDIC

PICS OF THE "RACK OF RIBS" (PLENUM) OFF WHILE REPLACING THE NEW PLUGS WITH MORE NEW "OEM" PLUGS

I'LL STICK WITH MY "REAL JEEPS"
