Doc had similar sorta issues with wife's Escape
Reckon my symptoms are sorta the same as his?
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!
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 --- (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
A new IAC for Sheets & Giggles!
Mega Vacuum leak search 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
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) 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 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, then buy a new one if solved the problem.
So happened, the salvage yard guy had a machine, in a stored code, it said #3 had misfired. My little scanner could not tell me that!
Runs perfect now, with the New $79 Coil Pack!
Always stick with a Jeep CJ, You can diagnose them, as you hear 'em drive by!
