Stalling :: 2007 Ford Taurus RPMs Stay At 2000 Or So For About 25 Seconds On Cold Start
Oct 4, 2015
I own a 2007 Ford Taurus with about 108k miles on it. When I first start the car, the rpms stay very high (2000) or so for about25 seconds. Once I start the car, until it gets all the way warm, the rpms want to stick around 1300 until I'm stopped for a few seconds, then they jerk downwards hard to almost 400 and come up to around 700.
After the car gets warmed up, it no longer sticks when I brake, but then when I'm stopped it lurches shakes and jerks between 400 and 1000 rpms. Occasionally it will die ( maybe twice a week) but then starts right back up again. I have replaced:
Air compressor
Idle air control valve
Throttle body sensor
I replaced the throttle body sensor yesterday and it seemed to drive better but it only lasted for about 12 hours then the next time I started the car it's doing it again. The only solution I've found so far is that it jerks just a little less when I'm in neutral.

In the first two years of ownership of my Passat, when I would turn the car on during cold days, the rpms would stay at 1500 for a quick 20 seconds until the car got a bit warm and then would drop down to about 800. Recently, when I turn the car on cold days, the rpms drop directly to 900 and below.

My 2000 F-250 6.8L V10 has a choppy idle during the first 30 or so seconds after a cold start up in the morning then it smooths out and drives perfectly. If I were to place the truck in gear during the choppy idle, it would not die and throttle response would be fine.
I cleaned the MAF sensor and checked the PCV elbow for cracks (no cracks). It idles at about a 1000 rpm during a cold startup then drops to about 750 rpm according to the dash tachometer. The truck has 187,000 miles on it.

Pretty much like clockwork. Every 9 seconds the power dies for about 1 second and then comes back on. Sometimes the Theft light comes on.
If I am at idle, the car dies. No check engine light. The car has had all new ignition parts in the last year except battery and alternator.

I have a 2006 Sorento, Idle at start, when cold is 2000 to 2200 rpms. When engine warms idle comes down to normal, 1000.
Replaced several vacuum lines, none showed any leaking but replaced to be sure.
Replaced the PCV valve, the old valve was not closing as it should and the replacement seemed to work some.
Replaced the Idle Air Control Valve and checked the old one for movement, moved an 1/8 of and inch from when cold to when hot. The new IAC did improve the problem some.
Tested throttle position sensor voltage, was good through range of motion (including being tapped on to simulate the running of the engine).
Sprayed carburetor cleaner around the engine when cold to look for a possible manifold leak, nothing noted.
Noticed one area that brings down the high idle when sprayed with carburetor cleaner is in the front top center, around a small plastic cylinder which is part of the intake system and has a vacuum manifold which changes the position of the cylinder with engine operation. I have two pictures of the area attached, the white cylinder is at end of paint stick, the vacuum manifold is to the right of the paint stick and yes there are vacuum lines not hooked up in the pictures. Hoping this is not a manifold leak.

I have a 2002 F150 5.4 2 valve. only when the engine is cold, everyone once in a while the engine will surge up and down about 2-300 RPMs for about 10 seconds. also right when I put it in drive it will surge. I was thinking about pulling off the trottle body and cleaning it.

I replaced my engine that had 155,000 miles with a newer used one with about 30,000 miles. since the swap my gas mileage is down by one third or more. Everything else seems fine except that my cold start idle is up to 2000rpm's until it drops to normal within 3 minutes.

Fuel pump does not work in Cold Weather, but works fine in warm weather? Will replacing the pump solve this or is there a bad sensor somewhere else causing the problem?

My 2002 Mazda MPV will stall everytime after the rpms go over 2,000 and I let off the gas. I can put it in neutral and it will start back up. Not sure if something is clogged or its electrical? It has 177,000

I have a 2001 Mazda Tribute with 150,000 miles that is meticulously maintained. This past winter (as far as winter goes in San Diego) the engine would run rough and the rpm's would drop close to stalling when stopping at a light for the first 2 or 3 miles. After that the engine has warmed and there is no problem. Could this be the intake gaskets needing replacement. This only happens on a cool or damp, rainly morning.

I had a Viper 5701 installed and it only stays on for 20 seconds then shuts down as if I was pressing the brake pedal. What is the work around? The hand held computer says the alarm is set for 12 minutes.

I recently purchased a used Camry XLE V6 with 90,000km on the engine. Soon after I bought it I noticed when I was stopped at a light the engine rpm's would increase for a few seconds at a time every 20 seconds or so. It was enough to make the car move forward slightly if my foot was on the brake lightly. I spent some time trying to re-create it at home, and it seems to do it consistently when the A/C is on, although some times it is more noticeable than others. It will do it when in park, or in drive with the brake on. The low (base) rpm is around 650 and it will increase to 950. It does this over and over as long as the AC is on. The rpm's will also increase if I turn the steering wheel when I am at a stop, but it only does it when I turn the wheel, it doesn't keep cycling. There are no check engine lights showing either.
I changed the air filter and cleaned the throttle body butterfly valve flap (not the entire throttle body) but it did not fix it. I also brought it to a Toyota dealer and they took it for a drive, but of course it did not show the systems as clearly that day. I didn't book an actual appointment with the mechanic though, since the car is running great otherwise and this problem is not bad enough to start throwing money at it doing problem solving. I also asked the guy I bought it from and he said it always did this from day one. If it were me I would have been making my dealer resolve it because it is not normal.
If I could fix this one very annoying issue the car would be perfect. I'm not sure if I need to do a full throttle body cleaning including the idle air control valve, or if this is more about the load on the engine and the way the computer/engine is responding to it.

How long do the glow plugs stay on during a cold start? Do the glow plugs stay on during the first few minutes of running?

My daughter has a 2000 accent , SOHC 12V, I think it's the 1.5L.. It will not stay running when the engine is cold...........after it warms up, or if it sits in the hot sun it's fine................it has 166K .
She said she took it to an auto parts store and had the engine code read, p1123 came up.....
Code P1123 : Long term fuel trim, at idle - mixture too rich..
What do you think this is caused by................ the inlet air temp sensor? I was told someone just replaced the air max flow sensor, that don't sound correct to me, but that's what they called it....probably the MAF sensor....

I have a golf mk4 1.8T AGU, about one week after i had my k04-023 turbo on and all the Stuff that comes along it started "stall" (don't know if its the right word??) in the High gears, most 5th gear but it first start doing it when i hit boost (3000rpm)
I runs on Stock n75 valve.. I though i could be a boost problem, maybe the Stock system cant handle it? I did install a boost gauge to see if it was the was the problem, and it dont Seem like it. In first it runs from 1.4 bar and drops to 1.2. Same in second and third. But in 4 and 5th it goes to 1.7 bar and drops to 1.4.. I did wonder it maybe the n75 valve cant handle 1.7 bar??

Can't find a thing wrong with it, no codes. Runs great down the street but backing out of the garage from cold start, it barely runs.

I have a 1996 Ford Taurus. With the headlight in the OFF position and the ignition off, key OUT, the headlights stay on. All other lights are off. The highbeam indicator in the cluster stays on also. I've disconnected the headlight switch (completely removed from vehicle), and the headlights still stay ON! I know absolutely nothing about this car.

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?

I changed the IAC valve 2 months ago because my truck kept stalling when idling down on a cold start and that fixed the problem. A few days days ago when starting it started revving to 2 - 3 K and won't IDLE down now? I changed the IAC again and that didn't work. What else should I be looking at to stop it from revving so high?
2001 F250 5.4 111,000 miles super duty.

The headlights stay on all the time & wear the battery down. I've replaced the DRL module with two new modules & neither fixed the problem. I even examined the headlight switch (some burn up at the switch), but this headlight switch & wiring look new. I even took the headlight switch out & the headlights still stayed on. I made sure that the new modules were grounded to the chasis properly.

I've noticed on first start up the RPMs go as high as 3000 for a couple of seconds and then drop to normal even at 68' degrees,is that normal? because if it is what will aspect when the temperature drops to 20 or even lower.It is a 2.5 liter 4.
