very rough idle
Hello,
This is the 1st issue, besides brake repair, that we have had with our 03 Escape 4x4 3.0L V6. Has about 60,000 miles, so far so good until this morning.
This morning, went to go to the store, truck started fine, but was idling very very rough, but never stalled. After driving for about 1/2 mile, check engine light started to flash.
I took it to Ford, and am waiting for the dreaded call. Any ideas? Clogged fuel injectors/filter? Oxygen sensor? Bad gas?
Thanks for your help

Could also be the IAC (Idle Air Control) valve. Not hard to replace.
Also MAF (Mass Airflow Sensor)
Unlikely, but possible, the DPFE (Differential Pressure Feedback EGR sensor) which is part of the EGR system....
When was the last time you changed your air cleaner? If really clogged, could cause problems...
The fuel injectors are self cleaning, unlikely
Gas filter...unless you bought some really dirty gas someplace...again unlikely
Oxygen Sensor...could be
Bad Gas? yea I get that every now and then Maalox helps.. seriously, when you say bad gas you mean gas that has been contaminated with water, kind of unlikely, but possible..

60k on the original brakes ain't bad, it's reasonable.
On the rough idle, I'd suspect a bad spark plug, bad gas is a plausible too. A bad egr can do that as well. If it was me I would have taken it out on an empty road and given it an italian tune up (basically floor the gas for a 1/2 mile or more in top gear), blow out any crap that could have accumilated in the engine. On my last car I had one of those foam shipping peanuts lodged in a new intercooler that I purchased, took the car out for a drive and the peanut got sucked into the intake system and the car ran like crap, stalled several times. I just took it to an empty road and gave her an italian tune up and everything ran perfectly after that.
good luck, keep us posted if you can.

well,
as you gentlemen suggested, it was a bad spark plug/coil pack on #5, and engine was temporarily running on 5 cylinders, thus causing the rough idle/check engine light.
Should be good to go now.

from what I see they only replaced 1 plug/coil pack....shouldn't these things be good for 100k miles? I understand there can be malfunctions, etc but hopefully my other plugs/coils will be good until the 1st scheduled tune up.
Thoughts?

well ive replaced coil packs/ plugs on my 02 and its not fun to do since you have to remove the intake and all vaccum lines attached to get to the 1,2,3 cylinders. it would make sence to me to just get it out of the way. unless your the penny pincher type (nothing at all wrong with that) but it should run for a good while longer. how many miles did you drive it before it was replaced? because as stated above raw fule in the cataletic converter is not good for it at all.
