Ford F-150 - 1997-2003 :: Truck Idles Very Rough - High Rpms Fine - Reason?
So my "farm truck" is idling very rough, to the point that sometimes that it stalls out. At high idle it runs fine but when its at a idle its very rough. Its been running fine until probably a month ago or so and its just getting worse. What it could be? I am thinking it might be that something is dirty but i just dont know where to start with figuring out what the problem is.

Today I acquired a 1982 F150 with a 302 engine, 4 brl. Edelbrock carb. The truck starts and idles just fine, but when I come to a stop, try to give it gas to go it dies. It starts right back up, and I have to rev it high a couple of times then put it in gear and it will finally go. When I got it home I let it idle a few minutes and tried playing with the air and fuel mix but don't know what I'm doing, really. It seems I can hear a hiss, and when I was reaching for the air/fuel screws I got a little shock on the hand from the distributor. We want to use this truck as a farm truck, and plan to get a manual for it, but what might I might check for the cause of it stalling.

2003 7.3 excursion.. The truck starts every time revs up and idles about 3 seconds then the rpms drop and it tries to stall out catches itself then revs backup and idles rough similar to if you have got air in the fuel lines from changing the fuel filter.. About 1 in five times the truck will stall out and it starts and immediately and idles rough but the rpms and everything runs at speed and rpms don't drop again! This is a reman engine/transmission recently installed.. The mechanic who installed it was unable to figure the problem out.

I've recently begun experiencing a problem with my truck dying immediately upon start up. It's a 99 5.4 and it will act like it's starting normally but then will idle down and die. If I gas it to 4000-5000 rpm it will eventually return to normal idle and run fine. At first it was once a week and then every day, usually upon the second start of the day but today it happened twice and I suspect it will become more frequent. What to check that doesn't involve a Ford Dealer?

2002 f150 4.6l v8... Truck is misfiring and the exhaust is smelling very rich, I have new coils and plugs, it also idles rough and stalls if i let it idle for more than a couple minutes. Could it be something with fuel delivery system?
View 1 RepliesPassat (B6) :: Starts But Then Immediately Stalls
I've had this intermittent issue for a while where the car won't start properly. What seems to happen to me is that it starts properly, but then immediately stalls. Normally during a start it will start at about 1200rpm then quickly idle back to under 1000 and then slowly reduce some more. Now at about the same time as I would expect it to idle back to 1000rpm it stalls. After this happens, it seems like I can keep reproducing the failed start over and over again if I try to start the car again. If I wait 30 seconds or so and then try to start it, it usually works.
On two or three occasions I got a warning on the dash about faulty steering lock. Checking in VAG the only errors shown are related to those, no other codes. This has happened many times over the course of perhaps two months. It's been colder during this period, but generally it seems the error happens more often when its a little warmer weather and not really cold. Lately I've been inserting the key part way, waiting a few instants for things to initialize and then starting and it seems to work every time.
Ford 6.0L Power Stroke Diesel :: F250 - Cold Starts Fine / Stalls Immediately After / No Throttle Low RPM
I'm having an issue with the truck not staying idle after cold start up. The truck will turn over and start right away (not even 2 second crank) but immediately dies. The throttle will not work at low RPM. When I start the truck, it will instantly rev high, the revs will drop low, it will try to compensate and rev high again, then it will immediately die.
If the RPMs are under under 2.5k, the truck will immediately stall and die. When I attempt to use the throttle under that RPM, it will not work. No matter how much I depress it, the engine will instantly cut and stall out. It will not attempt to deliver fuel. The only way I can get the truck started is if I rev the engine high and hold it. I need to hold the truck at 2.5k+ RPM for atleast 30 seconds. It generally takes me about 5 tries to finally get it running (mainly due to the throttle immediately cutting out and I have to 'catch' and hold it.) After that, there is no sign or issue. The truck will start immediately back up after it's been running for a couple minutes.
CEL: MAP sensor (0069?) -- Sensor is spotless. Harness looks fine. I replaced the injectors, both batteries, and the alternator this summer. It doesn't sound to be any these either as the truck sounds extremely healthy and immediately turns over.
Santa FE SM (2001-06) :: Starts And Stalls Immediately - Fuel Pump Bad?
I have an issue of fuel pressure I believe on my 2003 3.5 Santa fe...It would start then stall...I'm at my wits end with this thing...I checked the relay and its good...checked all fuses and they are good...I don't hear the 2-3 second whine of the pump when I turn the ignition to the on position, so I suspected a bad pump...but before I bought a new pump I took out the back seat, removed the access cover and checked the connector to see if the pump is getting power...its not...I'm at a loss as to where to look next...

When I try to crank the truck , it starts and immediately dies. This happened several times. The last attempt I began patting the accelerator when I turned the key. The truck cranked and I was able to keep it running by feathering the throttle. it ran rough. At higher RPM it ran ok. When I let it idle it idled rough. After engine warmed it idles and runs fine. Engine started without trouble when warm.

I have 2001 F-150 with 4.6L. Truck runs fine until under load and runs fine until I slow down to a stop sign. Once truck sits for a few moments it fires up again and will run for a short while then will do it again. Each time i let it sit for a few minutes, it will start again.
I pull a small travel trailer and seems to happen more frequently when pulling or climbing hill, but not under full power, just when slowing down. Could this be cause of catalytic converters? MAF sensor, or fuel starving.
Check engine light is on, will codes identify if it is a plugged cat?
Ford F-150 - 1997-2003 :: Truck Stalls Out In Gear But Not In Park
I had what I was told was the breather (on the drivers side valve cover) snap off. I was able to place a piece of tubing In it and reconnect it. I had to change the #7 cylinder spark plug wire. Got a misfire code and found the wire was loose and corroded. Replaced wire and PVC valve.
My problem is, it seems not to be idling as fast as it was before this happened. The truck stalls out now in gear but not in park. 1997 F150 4.6 ....
Ford F-150 - 1997-2003 :: Truck Only Starts In Neutral
I started having trouble with the truck only starting in neutral and it was a trick to get it to start even then. I bought a new range sensor, bolted her up (with alignment marks in neutral) and she's still doing the same thing.

Got this truck used, it is a 2001 F150 4 door lariat 5.4, 4x4. It now has around 108k miles on it. The truck dies while driving down the road every couple weeks or so. It will restart after a minute or so and then seems to be fine. The ABS light is on, no codes or CE light.
The last couple months while your going down the road it revs up to 4k rpms or so while your driving like the OD is turning off. The other day it wouldn't start in the morning, I changed the fuel pump relay and it fired right up. I put the old relay back in and it still fired up!!!!
I decided to take it to the dealer today and on the way to town it shifted out of gear while driving at speed, the speedo turned off and the odometer turned off as well. I shifted to N and then back to D, nothing, I hit the OD button and it flashed but still no go so I coasted to a stop, truck was running at idle.
I turned it off, restarted and everything worked just fine again and went on my way to the dealer. Still no CE lights.
Santa FE SM (2001-06) :: Car Starts Up And Idles At Around 2,000 Rpms
This all started out when I wanted to change my original plugs that had 200k miles on them. I have that part done now and new wires. Then it wouldn't start without me starting it while holding the gas pedal down. Then I would have to press the pedal down or it would die.
I may need to clean the throttle body. I bought some Valvoline Throttle Body Cleaner and cleaned the throttle body it was black inside and now it's nice and clean. After that the car starts up fine except on the first try. It starts up and idles at around 2,000 rpms. When I press the brake it drops to 1,000, then back up to 2,000. The strangest part is I have no acceleration power now. I can press the pedal to the floor and it will only go to 3,000 rpms. It will slowly get faster as I drive but there's no immediate response when I press the pedal down.
Why would cleaning the throttle body do this? It throws a code when I first start it and it dies the P1110 code but I think that is because the rpms are at 600 when it catches it. No misfire codes or anything, so I think the plugs and wires are working. Just the faster than normal idle now and no power when I press the pedal down.
Would the throttle body cleaner hurt the throttle position sensor?
Ford F-150 (2004-2008) :: 2007 - Starts Good Idles Fine Jumps And Shakes Over 800 RPMs
2007 5.4 . Starts good , idles all day. As soon as you try to rev it, it stumbles rattles etc. Shut it off, wait a second, restart then Idles fine. I watched live Data and it carries on when the VVT solenoids become active (above 800 rpm).There duty cycle goes to 60-70 percent while revving. I think it Is just one side of the engine. Could be VVT solenoids sticking on? yes ? No?

I have a 1997 forkd F150 with a 4.6L Romeo engine. I have recently rebuilt the engine and now since it is put back together I am having a issues that i cannot pin point. When the truck is running and in gear my RPM drop to around 500 or below and my oil pressure drops and comes back up when the rpm's come back up this an intermittent problem and I have replaced the IAC valve and every once in a while i get a P0401 code for the exhaust recirculation. I think I am loosing some kind of vacuum. It was not doing this when I tore into the truck. It seems to be running okay not hesitation.
