Ford - Gasoline - Pump - Mustang :: Idle Will Sometimes Get Really Low (below 1000 RPM) And Stall Out
Mar 18, 2011
When my 1998 Mustang has been stopped and started numerous times in a short period--say, like when you're running errands--the idle will sometimes (not always!) get really low (below 1000 RPM), and will stall out no matter how much gas you give it. It will then refuse to start for about 30 minutes. Then it'll start back up and run fine for another week until the whole thing happens again. The car runs fine in all other respects, and again, it's seemingly random, and only after the engine has been stopped and started several times. It won't for example, stall out first thing in the morning.

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.

My 88 "Rosie" has been having problems for months. It hesitates, stalls, and sometimes backfires. This is an intermittent problem, though it is happening more often lately. I took it to local auto shop and their computer showed Rosie was throwing a misfire code as well as a lean code. I took it 3 months ago, and I took it last week, got the same codes. The lean code led me to check the fuel pressure. I did and while it should be healthy 48-55 psi, I got 48 for awhile then 15 PSI! Now I'm thinking fuel delivery. I started with the filter. Sure enough it was dirty. Weeks later, the problem persists. I replaced the fuel regulator (ok, mostly because it was cheaper than the replacing the fuel pump, which I really didn't want to have to do.) Still, no luck, so I finally caved and spent $200 and 12 hrs dropping the tank to replace the fuel pump. Guess, what? Still no dice. I'm still getting the hesitation and the misfiring. I haven't put the fuel pressure tester back on it (been busy) so I don't know if the pressure is still low or if these other things are even related. I thought my logic was infallible. Let's face it, there's a finite number of parts that control fuel pressure. I'm running out of parts to replace. Where did I go wrong? The only thing I can think of that could still do it is perhaps the fuel pump relay? I dunno. Would it work off and on or fail completely? I'd love to get some opinions on this.

I have a 1989 Ford mustang 4 cylinder. The return line tofuel tank is leaking. I am wondering if I need to treat the return line as a "high Pressure line" or if I can repair with regular rubber fuel line and hose clamps.

I love my '86 Mustang GT convertible. Currently at 106,000 miles and running strong. The problem is searching at idle. I have replaced every sensor that me and my mechanic can think of. New plugs and wires along with rotor and distributor cap. The engine will start searching, i.e. idling up and down, and at time stall. If I apply slight pressure and idle up to 1,000 RPM the searching stops. Hard to do sometimes as this is a stick.

ok, i just became the proud owner of a 71 dodge dart.. fuel pump was not working, and am converting to an electric (airtex e8016s) and am told i need a relay. airtex doesn't seem to have one, is there another i can use? fairly new at this sort of thing, but have fixed a 72 honda motorbike, so not afraid of engines or whatnot.

I have a 2008 Hyndai Elantra with an automatic transmission. Since the first week I have had my car when the fuel is low (under a half of tank) the car tends to hesitate like it wants to stall, or momentarily shifts into a higher gear than it needs to be for the situation; the rmp's get very low. As the tank drops further below half full, the problem gets progressively worse, especially while trying to accelerate hard; i.e. entering the highway, starting from a red light, etc (times requiring a lower gear). I have brought my car to the dealer for service three times also asking them about this problem. Each time they can not replicate the problem which seems ridiculous since it is difficult to not have the problem when the tank is low.
The day I purchased my car I was speaking with another Elantra customer who was waiting for her car in the service department. She had just purchased her vehicle as well and already had to bring it in for a fuel pump recall. I believe the recall states that the fuel pump fails and causes the car to stall, sounds very similar to what my car wants to do. I have asked about this recall on my vehicle and have been told that it does not affect my car.

I have an '04 Subaru Forester which sputters and stalls after fill up. It sends error codes for cylinders 1, 3, & 4 misfiring...I only have a 4 cylinder car - This only started Friday - a few days later and I'm really getting desperate. I screw my gas cap on, we check the connections...and we've read all kinds of random solutions that spread across the board.

I have a 2000 Ford Focus SE with DOHC that is losing power and sputtering when it gets hot after driving for 30 min or more. If I shut the car off and right back on going down the highway it will be fine for 5-10 min and then start sputtering again. If the car is not hot this does not happen and I have a new fuel filter and coil pack as those are the two main things that I could think of. I have seen intake valve seat and fuel pump as the two most common fixes with similar circumstances.

I have a 2002 Ford Windstar that only in the fall and winter it has a longer crank time of at least 10 seconds. In the summer it starts as it should within 3-4 seconds. I did notice that the times it did start normally in the colder air is when I turned the key on and listened to the fuel pump prime the system. All other times it doesn't do that and that's when I get the long crank time. Once it is started it runs as normal. Am I looking at a possible fuel filter or pump? I am due to replace the filter as the van has 83,000 miles on it. If this is the possible culprit, is this something that is easily replaced at home?

Almost every time I start my 2001 Ford Focus, it won't start. The starter functions but the engine won't start. I have to pump it, give it gas, and once it starts, it's perfectly fine, no stalling, no problems after that. That is until I turn the engine off. When I go to start it again, say after doing an errand or two, it may or may not happen again throughout the day, the problem only occurring when I attempt to start it.

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've had the fuel injectors cleaned and fuel filter changed.I notice it when im at a stop light, dont know if it does it in Park. Iv been told if it was the spark plugs or wires that the check engine light would turn on, and its not on. What should I check next????

I have a 2008 Ford Focus - 4 Door Sedan SE 60300 miles.
I've gone to 3 mechanics now and no one can seem to figure out whats wrong with my car. Here's whats happening:
About 1 1/2 years ago I took my car to get an oil change at Jiffy Lube (Yeah never again). When I left, my car was idling funny... Silly me didn't take it right back and have them tell me what was wrong.. so I let it go, well about a month later it started idling even weirder. Basically it feels like my car is shaking when it gets under 1000 RPM and I notice my RPM dial start falling and bouncing back, acting like its going to stall, but never does. I notice a loss of power when this is happening (on speed up and just accelerating in general). All of this is random, I can't seem to put a pattern to it as to when it happens. One day I'll start it up and everything is perfect... Then I'll shut it off and restart it later, and it starts vibrating and puttering again... No signals as to if its hot/cold or wet/dry, no environmental variables seem to cause it to happen anymore than others. And there is no check engine light on, everything "looks" normal.
What I've had done to it so far is:
Air filter changed / reseated
3 oil changes (keep getting told it will work)
Throttle cleaned
Computer reset for idle sensor data rebuilding
Now I'm told that I need new engine mounts, and that could be the reason for the vibration. I'm thinking that the vibration caused the mounts to wear out, more so than the mounts being the cause. Mainly because I don't see how bad mounts could cause loss in power/bad idling.
What could be wrong?!? Really bugging me and don't want to keep throwing money at it for phantom solutions. Seems like mechanics I go to can't figure it out unless there is a check engine light on with some diagnosis code to tell them exactly whats wrong.

My car runs great except occasionally after I drive awhile, park and than restart to continue, it starts right up but stalls out 20-30 seconds later. I turns over but will not run. I have to let it sit for 30-45 minutes and than it starts up like a champ. I suspect fuel pump but would like an expert opinion. Garage says they can find nothing wrong and to bring it in when it happens... how do I do that.

I replaced the fuel pump in my 2001 chevy blazer last year and it just quit again two days ago. Internet research leads me to believe it is a common problem in chevy turcks. Blazer stops running, sits for a few hours to a day and then starts up again. Is it going to happen again and is it really the fuel pump.

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.

2000 Mustang was running fine. It hasn't been driven in a couple of days, and now wont start. No noise in the tank, fuel pump not working. But when you spray gas into the throttle body it wont even try to hit. Fuses under the hood beside the battery are all good. Inerta switch is down and in place. Am I missing something? maybe a relay? I would just think no matter what, getting fuel into the opening of the throttle would cause the car to at least cough.

My son has a Mustang GT 5.0 that is overheating. I replaced the radiator with a heavy duty 3 core radiator. It had underdrive pulleys so I replaced them with stock pulleys. I put dual electric fans on it. I flushed the block and put a new thermostat and replaced all the hoses (made sure the bottom radiator hose had wire in it so it wouldn't collapse). I put a new water pump and drive belt but it still overheats when sitting in traffic and overheats when driving with the A/C on.

I posted a few weeks ago about a problem I fixed with the MAF ( leak after the MAF ). 89 GT 111k miles, ( car restored to showroom condition ) Last week I pull to a stop light and idle is at 2000 RPM. Shut engine off and restarted and all was well, and idle back to about 800. I know something was wrong before hand as the car was pulling without my foot of the throttle. This happened again when I pulled into my driveway so let it run like this and when I pulled the plug on the IAC and idle dropped to about 600.
I took the IAC off the TB and cleaned it which did not look too bad. Installed IAC but left it disconnected and set up the idle on the TB according to the shop manual to 750 RPM. Shut engine off connected the IAC and followed the instructions in the manual to reset the ECU by disconnecting the battery for a few minutes, letting it idle for 2 minutes shut engine off then restart.
Well it was good for 2 days then started the same thing, 2000 rpm at idle..for the time being I have the IAC disconnected and set the idle up on the TB to about 850 RPM.
I have been driving the car like this for 4 days now and no running problems what so ever. Funny thing is no check engine light and no stored codes during this entire episode..Had my friend with an earlier OBD scan for codes and clean.
I hate shot gunning parts by replacing the IAC. Does it hurt running the car with the IAC disconnected or should I foot the bill and get a new one ? and hope that is the problem..or could something else be causing this ?
I checked for any vacuum leaks using my propane torch no change in idle. IAC problem on 89 Mustang GT 5.0 manual trans.?

I just changed the fuel pump on my 98 Isuzu Rodeo and now it wont start. The pump is getting power because i can hear it humming. Fuel is getting to the fuel rail, I checked the the shrader valve. I tested the battery and its fully charged but it wont start.
