Ford - Explorersport :: 1999 - Erratic RPMs When Idle And Rev When Braking
Here is a YouTube video showing my erratic RPMs while idling in park, then pressing and releasing the brakes and gas to show what happens each time: [URL] ....
I just bought a 99 Explorer Sport. The history I know is that the truck has 200k+ miles on it, with the engine replaced. Replacement engine has 90k on it.
Was told the fuel pump, and serpentine belt (I think, he said "main belt") were replaced in the last few months.
The car was driving fine on the test drive and for the first few days of owning it. Then a clicking sound started form under the hood while driving.
I first noted the clicking while at a red light, and when I accelerated it stopped. Over the last week it has increased in frequency every day and now is almost constant.
This evening I was coming to a stop with my foot off the gas and when I hit the brakes the RPM went up, and car lurched forward before stopping gently. This kept happening so I drove home and took the above video. Video taken shows the RPMs jumping up when in park and going form idle to idle with brake depressed. when I rev the gas and let go, the RPMs fall, hang for a couple seconds, and then fall back to ~1000. The captions are very accurate, they show exactly when the brake or gas was pressed and when they were let go.
My obvious question would be WHAT IS CAUSING THIS? Also, ARE THE CLICKING AND THE RPMs RELATED? Finally, SHOULD I AVOID DRIVING IT? I need to drive it a few times through the next few days and I can't really avoid it unless it will mean serious damage.
Ford - Explorer :: 2002 - Overheating Especially Going Uphill When RPMs Are Higher
Problems overheating. Have replaced thermostat and the housing for it...fan clutch and water pump. Its still overheating especially going uphill when RPM's are higher. How can I check to see if there is a radiator blockage?

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.

My car is a 2001 honda accord v6. It sat for 3 winter months. When I go to turn it on in the morning, the car will rev while idling. Jumping between 1000 and 3000 rpms. Why this might be happening?

I have several problems with my 06 FEH maybe some of you had same issues. I have imported this car from new york in my country 1 month ago, this is first Ford for me. Love this car but there is some issues and want to figure them out.
1. seat heating is turning on without clicking on the button, but not always it's random. Often on passenger seat some time on driver side to. I try to disable fuse but it also for 4x4 so it's not an option.
2. My engine idle RPMs is always higher that 1000. Maybe it is normal but want to be sure.
3. car cannot climb the hills here is the video.... car is just doing nothing to climb no rev up no trying just stall in middle. In my country there is some roads with hills like this and I want to visit that places.
4. Cruise control is working random to maybe it will start speed control in one click or after 20 -s try.
5.Is there any way to see soc? factory unis is replaced in my car with aftermarket radio. I have elm327 and tourque pro but can't find that option.
6. When monitoring with obd water temperature is always lower then it was on my other cars. its around 158-176F on other cars it was 200F.

Ford F-150 (2004-2008) :: Misfire Under Load At 40 - 60 MPH While In OD Or At Higher RPMs At WOT
I have a 2006 Ford F150, king ranch, 4x4, super crew 135k miles. I bought the truck and shortly after noticed the miss under a load at 40-60 mph while in OD, or at higher RPMs at WOT, but never a CEL. Well 3 months went by and I couldn't take it anymore so with lots of research I decided to change the plugs. Ran seafoam through 2 tanks of fuel prior to this job to break up the carbon in hopes of none of the plugs breaking.
All 8 plugs came out with no issue and I replaced them with the Motocraft SP 515s (old ones were very nasty and brittle, most likely the original). I put copper anti seize on the end that goes through the channel in the head, however none got on the end near the electrode, and also on the threads. Put it all back together and it had the worse misfire an pretty much not drivable....flashing CEL and codes p0308, p0355, p0356. So I decided to buy 8 new coils as well, got all 8 of them on and now the truck is drivable but the miss is still there (no CEL).
Feels like maybe just one cylinder and I believe I got it pin pointed to cylinder 8. I put a vacuum gauge on it and unplugged the injectors 1 at a time and cylinder 8 is the only one that there is no change while unplugged. So I switched out the coil thinking maybe I got a bad one, still does it. My COP electrical plug has 12v Constant and also confirmed with an led it is getting signal. The injector is ticking or pulsing as i confirmed with a mechanic stethoscope. What am I missing????? Today when I get off I plan pulling the spark plug, checking for carbon tracking, check compression, check actual visual spark, and pull and clean the injector.
Ford F-150 (2004-2008) :: Vacuum Leak Causing Erratic Idle - Codes PO171 / 174?
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?????
Ford Super Duty (1999-2016) :: Rough Idle And Stalls But Runs Fine At Higher RPMs - No Brakes
Let me start with I have a 2003 f250 5.4. The motor blew on my truck and I had a 100k motor dropped in it. I've put new spark plugs, ohmd out the coils. I tried both sets of injectors. cat delete and new fuel pump. It has rough idle and stalls but runs fine at higher rpms. Also has basically no brakes. I am thinking vacuum but I've check all the lines. No codes either!! also cleaned throttle body.

Ok, I have a 95 F150 5.0. It's sat for 6 months with the engine taken apart. I just finished putting everything back together with a new alternator. Well, I pulled a bone-head move and forgot to connect the harness when I fired the truck up. Other than not charging though, it ran fine. When I connected the harness, it began to chirp and shudder at low RPMs and squeal and vibrate at higher RPMs and it over heated VERY QUICKLY.
So hot the case was too hot to touch and the pulley smoked the belt. The engine didn't even have time to get up to operating temperature. I've had the alternator replaced twice, and this last one tested good putting out 14.5 volts. The work I did on the engine was to replace the valve springs, install a direct drive timing gear, replace a spun harmonic balancer, bypass the smog pump because it froze up, new distributor, a new ECU and O2 sensor.
Ford Super Duty (1999-2016) :: RPMs Jumping - OD On / Off Light Keeps Blinking
My truck is acting up. Last night when I was parallel parking I noticed the RPM was jumping, I then noticed the OverDrive switch was blinking. I turned off and turned it back on and the issue went away. This morning on my way to work, it did exactly the same and it automatically corrected itself. The overDrive ON/OFF light keeps blinking.

Ford F-150 - 1997-2003 :: Vibrating / Loud Noise When Accelerate / RPMs Jumping Around
I have been having some major issues with my truck!
The whole truck is vibrating when on. When I accelerate I hear a loud noise like something is hitting a fan. I'm scared to even drive it. The rpm's have been jumping around.
What could be causing this? I already replaces Fuel filters.
Ford F-150 - 1997-2003 :: 1998 - Truck Is Jumping From 1500 To About 2500 - 2600 RPMs
So my 98 f150 xlt 4.6 is having a issue where the truck is jumping from 1500 rpm to about 2500 - 2600 rpm. You know sitting there trying to get up to speed. then all the sudden i look down and its at 1500 rpm. but still not really going anywhere. So i give it a little more throttle or gas and it jumps from 1500 to about 2500. Its been like this for a month but i thought it was crap fuel. What is the cause or maybe a solution?
View 4 RepliesGolf/GTI VI :: Jumping RPMs While Accelerating
I've been trying to figure out what exactly is going on with my car but its hard to explain/describe it so I've decided to video it..
Driving + shifting + holding my phone + my GTI is spun all the way down on coils = shakie video.
In Video #1, I'm in 4th gear at 2800 RPM and gave it full throttle. Watch it closely at 0:04 you will notice how the RMP just jump back a little and then continue accelerating while the boost is holding at 15psi.
Video #2, same story at 0:04 except the boost jumps back as well.
It does NOT seem normal and im not sure whats wrong and where to even start.
Slipping clutch?
Diverter Valve?
Boost/vacuum leak?
Turbo into DP leak?
My GTI is APR Stage II, intake and catless turboback exhaust.

Ford F-150 (2004-2008) :: Rough Idle / Bad Gas Mileage / Stalls Out / RPMs Jumps Around
I bought an 04 f150 super crew cab with the 5.4L triton in it 3 years ago with 50k on it from my great uncle who was the original owner. It's had a tick to it since he had it but the dealership told him they couldn't find anything wrong with it and to get use to the noise. It's ran pretty good up until last couple months where it's been running really rough and not doing the best. It's still hasn't been all the time but more intermittent and comes and goes, but when it's running bad the rpm drops down to about 200 and my motor sounds blown.
When that's happening I could put in neutral and rev it up and it would go back to normal for a bit, but now it's all the time and stalls out even at 70 on the hwy. The codes it throws are, p1000- monitor checks not complete-more driving required, p0345- camshaft pos sens circ error(bank 2), p0022- A camshaft pos timing-over retarded bank 2. Things I have tried-changed all 8 plugs, added K&N air intake, replaced both cam sensors, replaced fuel pump driver module (due to corrosion). Tonight I'm going to clean the throttle body, mas air flow sensor, change fuel filter.
Golf IV / Jetta IV :: RPMs Jumping And Car Is Stalling
I have a 2001 vw jetta 2.0l manual. When the car is running the rpms jump up and Down from about 300 rpm to 900 rpm and I guess that's why the car will stall out every time I press the clutch to stop. Also the car won't run with the MAF plugged in. If the MAF is plugged in it will drive but will not idle the car will just stall.
View 16 RepliesPassat (B6) :: 2006 - RPMs Jumping Around While Coasting
I have a 06 B6 that I am having issues with. We took a trip to Vegas in June and had no problems the entire way. We get home and the next day he starts throwing a CEL. We take it to our mechanic to have him VAG COM it and he says it is running rich at idle. The mechanic says that we may have gotten some bad gas when we left Vegas. Ok, no worries, we put new gas in the car along with some fuel cleaner and it seems to be ok. I drive the car 7 miles each way to work, and the way I break is that I coast into it before I brake. I noticed that the RPM's started jumping around. My husband took it to the mechanic and he said to clean the MAF and to take the intake off. Done, still getting a CEL.
So I take it back to the mechanic and he says its the seal inside the High Pressure Fuel Pump, while because of the CamFlower/Fuel Pump issue the only one in Phoenix is 50 miles away and at an Audi dealership that wanted to mark it up 50%. He also said that it smelled like fuel under the oil cap. So I go and get it, only to get it put on (Wednesday), everything good and then I notice today(Friday) that it is still jumping around. I have had the code cleared today but I am afraid that it is still something else. The CEL is off but for how long I dont know.
Elantra XD (2001-06) :: Losing Power After Logging 250 Mi / RPMs Also Become Erratic
I'm currently moving cross-country from LA to St. Louis. Had routine maintenance done b4 I left. I've only made it to New Mexico so far b/c my car is losing power after logging 250 mi. RPM's also become erratic. Doesn't completely stall, but won't let me go more than 45mi/h. After a rest break, the problem doesn't re-create.
At my first mechanic stop, the computer checked-out as ok. That mechanic changed the spark plugs and also told me the 2004 has no fuel filter (fuel filter being my suspicion of what was wrong).
Today it lost power again. Jim Bob at a rural garage said maybe the alternator or fuel pump. I have an appt. at Pep Boys tomorrow, as the dealers don't have any avail appts. until Fri.
The contents of my apt. are in the trunk and backseat. Is it worth it to remove them (to get to the fuel pump) at the cost of another hotel day, or should I limp home at 250 mi. a stretch?
Ford - Mustang :: 1994 - Erratic Idle And Stalling
I have a 94 Cobra Mustang with a 5.0. For the past few months it has had an erratic Idle and stalls when trying to idle. I've had a number of suggestions on how to fix it and nothings seems to work. I checked for vacuum leaks, changed PCV, new plugs, new IAC valve, tested ICM and throttle TPS and even adjusted idle. Still no luck.

I have an 01 f150 4.6 4x4 automatic with 90,000 miles. I have an erratic idle but it only happens when I am on the freeway well actually when I get off the freeway and stop. the idle will fluctuate between 750and then drop to 400 then back and forth til I get moving again. I replaced the IACV because it was doing the weird humming and vibrating the intake tube. The humming is gone but still idles funny as stated above.
