Ford Excursion :: V10 - Hanging Idle / High RPMs
Jul 22, 2013
Not really sure if the V-10 is supposed to be this way or not. I've had quite a few of the 4.6 and 5.4, both the 2v and 3v variant. Never had them do it.
Basically, my V-10 doesn't idle down easily. I can do a neutral rev and it will hang out from 1,000 to 1,500 rpm for maybe 2-3 seconds, then drop to normal idle revs.
While in gear and slowing to a stop, it feels like the motor is fighting the brakes and I have to press harder to stop. It also comes off the transmission when going 35-40 mph and letting off the gas. Causes a weird lurch if I have to get back on the gas.
Not dangerous or anything of that sort, but very very annoying. And I feel it's costing me some MPG's since I drive 99% city and have lots of stops. Probably 1-2 MPG at max. Back in my 2v Mustang days I remember some of the guys were modifying the 4.6 2v IAC because of similar complaints. I'm trying to dig up that mod, but it's been a few years.
I plan on cleaning the IAC this week when I get the time

My '00 V10 4x4 w/ 163k miles has had a rough shift from 2-3 (30-40 mph) with high rpms. If I let off the throttle before the shift I can get it to shift smooth, but if I don't let off the throttle it can shift really hard. I only have this issue from 2-3 and it has not gotten worse since I bought the rig almost two years ago. Driving conditions are around town on occasion and for towing a 3k pound pop up. Maybe 2k miles a year so far? The hard shift happens whether towing or not.
I have done just a drain and fill on the trans fluid a year ago. Have not had time to change the filter (even though I have read it's not necessary). I am planning on doing another drain and fill soon along with the filter since I have one and cleaning out the trans pan.
When searching on FTE I read a post about the accumulator springs that can go bad and was wondering if maybe this is the problem? Since I am planning on doing the filter change I was going to do the spring replacement while the pan was open.

I have a 2003 Ford Musang 3.8L v6 when I start my car for the first time of the day or after several hours of sitting the car idles high between 1000-1300 RPMs for approximately 15-20 seconds after that it idles down to 600-800 rpms. I changed the spark plugs wires air filter not sure what else it could be no Check engine light.

1999 B3000 with a 3.0. The truck idles at 850rpms. When it starts it idles at around 1000 and runs very rough. When I disconnect the IAC the engine dies. The AC also has problems it blows cold at idle but at highway speeds after 7-8 minutes running the compressor kicks out. One can turn it off and it blows cold again after a few minutes.

When I start my 2003 Escape 3.0, the rpm's shoot up to about 3000rpms. After a few seconds they drop to about 2000 and slowly creep back up to 3000. When I put in gear, I don't even have to step on the gas and my vehicle goes. It maintains between 1500-2000rpms as I'm driving. When I come to a red light or stop sign, it lurches like it wants to go even though I have my foot on the brakes. I've replaced the IAC valve, TPS, had it checked for vacuum leaks, PCV valve replaced. I'm at a loss as to what it could be.

So I just purchased my first diesel a couple weeks ago (2003 f250 Lariat). I love it! However, I'm having concerns about my turbo whistle on it. At idle and while in higher RPMs is sounds ridiculously loud (even at 0 PSI in the boost). I've been doing my research on it and I know the 03's have the loudest sounding turbos because they have less vanes than the later models. I know without a video it's going to be hard to diagnose, but I am wondering if a loose boot would cause a turbo whining sound through the exhaust? I have yet to hear ANY other diesel in person that has a turbo whine as loud as mine.

2012 SEL... Experiencing High Idle (1000 rpms) when the AC is ON. When I power the AC system OFF... the idle comes down to 700-800rpms. Then I power the AC back ON and it stays for the rest of my trip. Restart the car, and it's back to 1000 rpms with the AC on.

I purchased a 2000 4X4 V10 with 63,000 miles. It sat with very little movement for 12 years or so. I have been driving it for a few months and it now has 73,000 on it.
To my question. I have an high idle after start up. After the engine starts the idle goes up to 2K but comes back down to normal(1K or so). It takes a second or to 2 for the idle to drop. This seems strange to me. Is this normal? I've done some searching and found plenty on high idles but none seem to fit this condition.

I have a 2005 6.0L Excursion. I'd like to do the high idle mod. From looking in the tech folder there are two options.. Option #1 being for 2003-2004 trucks and Option #2 being for 2005+ trucks. The assumption for Option #2 is that there is wiring from the factory for the upfitter switches. My engine build is a 2004 and I could not find any evidence of the orange upfitter wires so I proceeded with Option #1.
I find wire 294 (white/light blue strip) with no problem.. What I can't seem to find is wire 322 (light blue/yellow strip). I can find the 4 dummy (extra) wires to the engine compartment (Red, White, Blue, Black solids) yet I only find 3 blunt cut wires capped with tape... The colors on those are white/orange strip, light green/white strip and yellow/white strip - no sign of the light blue/yellow strip wire.
Is there something unique about the 2005 Excursions?

I have a 2000 X V10 and am having an intermittent high idle condition. I have searched the forums and found some useful info but nothing that addresses this issue. Here's what I've done. New IAC, found PCV valve hose leaking-replaced also new valve, found another vacuum leak-repaired, tested TPS and that was fine according to the specs I found. So here's my problem-upon starting engine occasionally "stumbles" then roars to life idles 8-1100rpm. Drives well till stopping at an intersection and idles 1100-1200 rpm.(lots of brake) Can pull into parking spot place in park and will idle up 1500-1800 rpm and then only drop to 1200 or so. I have checked everything I know. ALL these idle conditions are INTERMITTENT. (and yes I did check for codes "0" ) There is no loss of power.

I'm trying to find out what I need to check or replace to get my 2000 Excursion to idle at normal rpm's in park and neutral.

My friend and I both have the MK4 R32. He had a bunch of stuff replaced in the engine. (a bunch of plastic parts that are super expense, the timing chain, something related to the guide, basically the plastics that holds the engine cushion/absorb) Anyways, his engine sounds great and quiet at the same time with a little high pitch noise when the RPM is hanging in between 1K and 2K.
Our cars were in the garage and I did the same thing and it sounded NOT quiet, a lot more noise than his. There was an obvious difference in noise coming from the engine with the hood open. I do have cams and a light weight pulley. Can that have an affect on the engine noise? If I am not making sense, then i should probably video record the sound or take it to the dealership for a check up. Also, I am at 93K.

My check engine light came on today and while driving, the idle (RPM's) were very high. At about 80KMs, it was about 3500 and when I accelerated, the engine would race along with the RPMs. While stopped, idling seems fine. I couldn't get over 80KMs/Hr without the idle going too high.
What it could be? Haven't had time to check codes as it is long weekend and garages are now closed till tuesday.

I just changed my alternator because it was making a whining sound off/on, then just went completely dead. I got it back from the shop and that certainly fixed the problem. However, I now notice a very faint high pitch ringing from idle to 2.5k rpms or so, I hear it more so in the cabin. Also, if I hold at 1,500 rpms now the engine vibrates and stumbles right at that holding point, it didn't do that before. Is there a chance that this remanufactured alternator could be the problem?

Had a first-time issue with my car today. Background, 2010 II bought in June, just short of 15K miles, never had any kind of mechanical issue.
While en route to work this morning, I was about halfway into my 15 minute drive to work, when I noticed my engine was idling very high, I would guess 2500 rpms. It started doing it while I was driving around 35 MPH, then continued doing it while I stopped at a traffic light, and continued when I continued driving to a speed around 50 MPH. The high idle while stopped was not transferred to the wheels, so it was not a safety issue as it would be in other cars.
When I got back up to 50, curious to try something, I hit the ECO mode button and the car returned to normal. I took ECO back off and the car was still fine. I had no further problems.
I would point out that this morning was about the coldest temp that the car has experienced. Outside temp ranged from 7 to 10 degrees.

My friend was having trouble with her 2001 elantra. Her idle was erratic and her RPMs were constantly high. we checked every where for a vacuum leak but could not find one in any of the lines. We went on to switch out the idle air control valve, the throttle position sensor, and even cleaned out her throttle body. we threw up our hands and sent it to a shop. Come to find out there WAS a vacuum leak. apparently in the air idle control valve sensor there is a gasket that seemed to be missing. I of course didn't think about replacing a gasket when I replaced the sensor because I never saw one there.

2004 Santa Fe .... 2.7 6 Cyl 4WD 150k miles
Recently I started experiencing RPMs surging upon startup and driving before my engine warms up. The problem has gotten worse to where I push on the accelerator the RPMs jump to 2700 and the transmission feels like it disengages. My initial thought was the tranny was going bad and slipping. I checked the fluid level in the T and found it was maybe a half Qt. low. I topped it off, but this had no impact on the problem. On a side note, I am able to use the manual shifting feature on the "His and Hers" Shifter and drive the vehicle without any issue. Transmission works fine in manual. The surging RPMs which only occur in Automatic mode, triggered the CEL and I got a code of P0123 which is high side voltage on the Throttle Position Sensor. I replaced the gray TPS with a new black one.
Upon startup the RPMS jumped to 3000 just sitting in Park. I disassembled and reinstalled figuring I had something bound in the throttle. After reassembly the idle went up to 2200, still no good! I reinstalled the original gray TPS and the RPMs, upon starting, RPMs were 1500 with the old sensor...still too high. I did reset the ECU twice during the process of putting in the new sensor and reinstalling the old sensor. Right now I found that when I disconnect the TPS electrical connector, the engine runs normal. It starts right up with the TPS totally disconnected and idles at 750 RPMs! It will not shift to 2nd gear though, when I try to drive it in Automatic Mode. I can however drive in Manual Mode and drive normal and shift right through the gears. Who needs automatic mode right?!!!

So I had this issue with my idling at 1300 rpms but every now and then it would idle at 400 and barley run then one day it didnt want to idle at all so I checked the iac and it was bad so I changed my oil, fuel filter, iac, cleaned my throttle body, fixed a vacuum hose, and cleaned my air filter.
When I started it it idle at 2200 I drove it a little and it dropped down to 1300 the next day I started it and it idled at 800 and staid there for four days now it idles at 2000 then will drop down and surge between 1300 and 1800.
I read that the oil you apply to the filter can contaminate the Maf and you should clean it but a lot of people said the one on a vr4 can't be cleaned while others say it fine. Is there a way to check the maf?

Just checking in to see where you'd recommend to start looking for a rough idle issue. It seems to get worse once the car fully warms up. I took a vid, and although it may not seem horrible in the video, it sometimes causes throttle lag from a stop and causes the car to get close to stalling when falling from high RPM's. Take a look at the video .....

1995 Honda EX with 150,000 miles. Its been running rough ie rough idle, stalling at low rpms etc Additionally for awhile now when humidy reached north of 85% the car wont start. It cranks but rarely runs.
Took it to a mechanic last week for a tuneup. They replaced the Distributor cap, spark plug and wires and fuel filter. Car ran great for a day. Then progressively got worse. Was undriveable the other day stalling misfiring while at speed. Took it back today. They determined that it was still not getting spark and replaced the distributor. They did so, test drove it, declared it good and I came to pick it up. Paid the bill, walked out to the car and the damn thing would not start. Humidity was high.
Mechanic pulled a spark plug and put a tester in and didn't get a spark when cranking. He is assuming the distributor he just put in is bad. So they are keeping the car overnight to be fixed in the morning with a new distributor.
However I'm not convinced the dizzy is bad, I believe, as I've read that the Honda's ECU is probably bad and shorting out in the high humidity. Can a bad ECU would prevent spark?

My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.
Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.
What could be the problem? Could it just be the battery?
