Ford Escape / Hybrid :: 2001- Erratic Idle Speed Due To Vacuum Elbow Collapsing?
Jun 18, 2014
I've read quite a bit in various threads about the large vacuum elbow collapsing, causing erratic idle speeds. My 2001 3.0 had that issue int he past. I shoved a 1/2" copper 45 degree elbow inside of the rubber elbow, and the problem was solved... until a few days ago.
We're now getting into the hot part of summer here. I've notice the same symptoms are beginning to return, once the engine compartment gets hot. My question is... is the large vacuum line a "hard line" all the rest of the way to the engine, or are there other places along it's length that can also collapse under vacuum?

I simply cannot find a proper and complete vacuum diagram for this 2001 Escape V6. (The sticker has been removed from the car.)
The car is hard to start - very hard, but once warm it manages to run ok. There vacuum hose way down low, on the back of the block and under the starter, impossible to see but if my fingers aren't lying it's very near the knock sensor? This hose is rotten and disconnected at the top - it's just laying there kinda under the throttle body.
For the life of me I cannot a) identify what the hose goes to and b) figure out where to plug it back in. There are no empty ports I can find anywhere within reach of the floppy end of the hose.

I have a 2001 Escape, V6 engine and I guess it really does not like it when it's cold outside. Usually the car runs just perfect but when the winter arrives and temps drop into the 20s the truck does not want to run idle right when I first start it. I have tried by stating it without touching the gas pedal. And also by pushing it all the way down and then releasing it. I don't know which method is the right one, but it doesn't seem to make a difference. It takes some time and eventually after about 5 miles of driving it will act normal again. What could I do to fix that?

I've got an 01 Ford Escape 4 cyl 5spd awd, it idled low when its warm, revs between shifts and if you put it in nuetral and let the clutch out when you're moving it revs to 3500rpms and just sits there until you stop or push the clutch back in. I've replaced the iacv and the pcv valve, elbow and hose, and the tps. What to look at next?

I'm needing cold engine misfire. 2001 escape 3.0 engine 190300 miles on it. I changed the plugs, cleaned the fuel injectors, new air filter, new fuel filter, cleaned the pcv valve and new ideal control valve. When the engine is cold it starts right up but wont idle right and misfires sputters some to but run the rpm's up and it smooths out. drop to idle and it misses. Now when the engine gets to operating temp it seems to run fine. What am I overlooking to find the problem?

I tugged on the little hose on the back pass. side of the engine,(5.4),...
and I could hear the vacuum leak that is apparently causing the erratic idle, and PO171 & PO174 to come up.
I know this hose is hooked to the Charge motion Control Valve on the back of the manifold,..I can't imagine what it does, as it terminates with some kind of plug or check valve??? Haynes say's to remove the entire manifold to get to the CMCV.
I can see it with a mirror,. I am thinking maybe long needle nose from Harbor freight,...bend the tip short,..maybe be able to change it out?????

I have a 2004 Ford Escape 3.0 V6 FWD, and the air conditioning has been blowing only to defrost for a few weeks now. After many searches online, most sources seem to agree it is a vacuum leak, as the selector switch is vacuum driven if you want anything except defrost. I popped the hood and within one minute I found one open vacuum line that looks like it has been worn in two.
The line in question goes from the vacuum canister towards the passenger side of the firewall, then goes to a T connector, then a line (the one that is broken) continues towards the heater core lines to where the break in the line is. I found a picture online of what it should look like, but I am having trouble accessing the line that goes through the firewall and behind the glove compartment. I am pretty sure this vacuum line continues through the firewall between the two heater lines, but after that I am stumped.
I popped the glove box down out of the way and I see two thin vacuum lines and a small metal "can" nearby. The black line goes from a fitting and into the A/C bundle, and the white line goes from the top of the metal canister and down into the same bundle. My main question is which line controls the AC selector, and how do I pass a replacement line through that part of the firewall to make a good connection, as it seems the break is at the firewall itself with no extra sticking out for me to connect to.

I have a V-10 in my Y2K F-250. Under the throttle body there is an elbow on a vacuum line that is badly cracked. I went to parts store and bought a heater line that fit both ends (different sizes) but isnt the exact angle of the original. It fixed the hissing vacuum leak but now it is running pretty rough. Doesnt seem to be pinched but it's definitely different. The poor performance during acceleration wasnt a problem before but is very noticeable now. Could the line being different effect the performance?

Just wanted to post a recent experience I had with the catalytic converter issues Escapes seem to be prone to. A friend has a 2003 Escape 4x4 with the 3.0 V-6 and automatic transmission. It has 141,000 miles on it, she bought it with 40,000 miles on the vehicle.
Recently it developed driveability issues: No power with a whistling noise and top speed of 10 M.P.H. I researched on here and her symptoms matched threads that came up using the search function. I told her I was pretty sure the front cat was bad and had plugged the rear cat, causing the issue. She took it to a local repair shop and confirmed my diagnosis. Their estimate for repair was north of $1,500.00. My neighbor and I were sure we could repair it cheaper.
We towed it to my house and pulled the front and rear-most cats. As suspected they were both bad. The back cat on the engine looked pristine inside so we left it alone. We ordered all of our parts from rockauto. New front and rear-most cats, exhaust and intake gaskets, serpentine belt, and one O2 sensor that was damaged when the insides of the front cat let go.
Installation was straight forward with no major issues. We also changed the plugs with brand new ones she had purchased but never had installed. The vehicle now runs fantastic and she is extremely happy with it.

ok this has me stumped I get this buzzing/humming/vibration sound from what seems like around Defroster passenger side but it is not all the time only at higher speeds and it it intermittent . I have removed cabin filter and cleaned filter box and checked for a leaf or something even sealed somewhat the plastic shield that covers the cabin filter. I really don't want to rip dash apart but it is so annoying

I'm experiencing the tug/jerk/shuddering in my 2012 Escape v6. It happens more around 70mph or 2,000-2,500rpm.
Tug/jerk/lurch/buck happens even more with OD off. Happens around 60mph or 2000rpm with OD off.
Been to the dealer several times even test drove with a mechanic that acknowledges the tug/jerk sensation. No codes or faults. Last visit the dealer showed me a print out of misfire counts and all cylinders were 0 yet on the drive home it was tug/jerk/lurching.

I have noticed that my vehicles engine fan runs at max speed (and is very loud) all the time. Regardless of outside temperature, engine temperature, climate control settings, etc. It runs like that from the second I turn it on until I shut it off.
I have done some research online and found that people with a similar concern have been told that it could possibly be either the Coolant Temperature Sensor and/or Cylinder Head Temperature Sensor. I know that it could be a wide variety of issues, however it seemed as though these were common (and relatively easy) solutions. Does anything think either/both of these could be the problem? If so, need info about the proper part and instructions/video on how to install the new parts.
I would much rather spend ~$50 for two parts than screw around taking it in. If my attempts dont work, at least I know that I have 2 new parts in there. Or is this not really anything that I should worry about?
Additionally, my climate control settings dont all work. And I have found through research that I need to replace the blower resistor. Would this have any impact on the engine fan? I drive a 2012 Ford Escape XLT 3.0L V6

Recently picked up a 2007 Escape with 108,000 miles. The vehicle is in great condition with a full service history. Recently I've noticed a bit of shimmy in the steering wheel and noise from the front drivers side wheel accompanying the shimmy.
At speeds of 50mph+ the shimmy will start. When going straight there is not much of an issue but when a gradual right hand turn on the highway the shimmy starts. Back to straight and it goes away. Not really noticeable on left hand curves.
Steering issue?
Tie Rods?
Bearings?
I'm going to dig into it to get it fixed.

I have the 2.0L 4 cyl. engine (2001 XLS Manual 114k miles). Runs fine when cold but once the engine gets warmed up it starts idling really low. I mean so low that the RPM gauge looks like the engine is turned off, although it hasn't completely stalled (yet). The engine will kind of stumble here and there and occasionally jump up to the normal RPM. Not rough really (in fact it's hard to tell if the engine is on when it's so low) but something is obviously wrong. The check engine light is not on (assume no codes?).
Also when I'm driving I can feel that the RPM's are unstable and erratic. You know, it feels like I'm pushing and releasing the pedal very slightly even though I'm not moving it.
I replaced the spark plugs and fuel filter since they needed to be done anyway. I checked the vacuum lines and they all seem good. I replaced a few deteriorated lines even though they were holding vacuum. None of this changed anything.
So now I'm looking at more expensive stuff like the throttle position sensor, idle air bypass valve, EGR, MAF, etc. Where I should start? Is there anything that I can actually test to see if it's working or do I just need to start replacing parts until I find the problem? I guess cleaning the MAF and IAC might be starting points that don't cost anything (that IAC looks difficult to remove though).
I'm kind of thinking it's the TPS since it feels erratic at speed. However, I have never had a bad TPS cause a slow idle before. I have had it cause rough idle and such but not slow. Can it do that? What about the MAF sensor?

I have a 2009 Ford Escape XLT, 4 cyl. and in the summer I had the vehicle in as the speed sensor failed. Since that time I have an ongoing ticking sound (sounds like a diesel vehicle). I had the vehicle into my local dealer and after looking over the vehicle they stated that it was "normal". However, my warranty is up in January 2014 and this sound is horrible. Below is a video of the sound.

I have a 05 escape hybrid with 75k on it. there is a slight problem every once in a while when it starts the idle jumps up and down and when it is put in reverse it has no power to move. you have to put the pedal to the floor....there are no codes and ford has had the car for a total of three weeks, nothing found and of course it did not act up for them..

My wife has her 03 escape v6. It has a very rough and low idle. On start up it idles nicely and then the idle drops and pulses if that makes any sense. I've pulled I think its the idle control sensor. It killed the engine as soon as I did. I've cleaned the throttle body.

I test drove 2 2005 escape limited v6 2wd today. Both of them were pretty loud in the cabin at idle. The noise and vibration did lessen after the car started to move. Is this normal for escapes or does this indicate a problem somewhere? Like engine or transmission mounts.

My g/f's 2004 Ford Escape (3.0L V6 AWD 112,000mi) is acting up. After a full day of sitting, with the second half of it raining steadily, she was driving her Escape and it was acting funny (miss-firing, she said). The engine light came on and soon began blinking. She got to my house shortly after it started this. We left it and I drove for the day. Later that night, I drove it and it seemed fine. The engine light was on, but not flashing anymore.
The next day I took it my friend that was a Saturn mechanic and now working at a KIA dealership (same owner as the former Saturn and current Buick/GMC and Chevy Dealer). It ran fine for me. So he tries to scan it, his Mac Tools scanner won't read it. The KIA scanner wouldn't read it. I drove it the Ford dealer up the road. They said they couldn't get to it until after lunch, I just want the codes read. They re-iterated, and I told them to pound salt and went to an independent shop where I know a guy. They read it right away for me. "Mis-fire on start-up" & "Cylinder 4 Mis-fire." were the two codes stored. He cleared them.
She got the tune up basics (plugs, wires, air filter, etc) and did the complete tune-up herself yesterday. (I was impressed). She put 94 in the tank and some fuel system cleaner in it as well. She said there's been no change and today I finally saw what it was doing. Sometimes during idling at a stop light, the RPMs will drop to almost zero, the lights dim but so far it has not stalled. It'll do this for several seconds, then correct itself and idle normally.
Currently, the engine light has not come back on. She's thinking coil pack (each cylinder has a coil on these engines) on #4. She wants to switch it out with #1 and see if the problem follows. I think that might uncover the cause, or it could be the battery. It's the original, never been replaced and has a lot of miles on it, but it survived this past winter, without trouble. In my experience, most batteries crap out due to age in the fall when the cold snaps start.

I have been having this problem with Gf's car for a few months it is a 06 3.0 escape with 141K on the clock the car seems to run ok except at red lights and when in drive it seems to idle like its just about 100 rpms low when I give it a little gas just a touch it smoothes out. if I put it in neutral the car smooth's out but in drive when you come to a stop light or stop sign you can feel the rough or low idle in the steering wheel. She is nagging me and it has been very cold here in Pa and I'm trying to wrap my head around if it is a cold thing or just a coincidence. I'm fairly good at wrenching and I just need some things to look for as when you start the car up cold it idles fast like 12 to 1300 rpms and then drops to about 900 and in drive it seems like maybe it's about 600 to 700 rpms. but where to start to look Is it a sensor, vacuum leak ?

When started very high idle after hitting gas pedal sometimes it will lower idle sometimes not,,then holding pressure on gas pedal it has very bad surging ... Any guesses what might be and possible cost fix?? I am no mechanic,will have to take it somewhere...90,000 miles on it..
