Ford Ranger / B-Series :: 1999 - Stalls In Hot Weather / Low Idle Otherwise
May 3, 2013
I have had my '99 Ranger since 2002. Since it has started getting hot in Texas, the truck has decided to stall at horrible times. When driving on the interstate, there is no problem, but as soon as I get in town and have to let off the gas to turn or stop, the whole truck dies. Unless it sits for a long time, it will continue to die at every stop. It is harder to start each time. I have changed the fuel filter and added STP to the last tank of gas. Also, it is tough to start and keep running until it has warmed up on any day. I have to sit in the truck and keep the idle up so it won't die.

I have a 1999 B4000 4.0L with 160K miles on it. Bought the truck new. Up until about a year ago it ran perfect but has developed an idle, stalling and occassional jerky ride problem. It occurs at any temperature, engine hot or cold, A/C clutch on or off and in Park, Drive or Neutral. When you start the engine it will not idle unless you keep your foot on the gas. The idle speed will drop to 200-300 rpm and the engine dies. Sometimes you can barely tap the gas pedal and the rpm will shoot up to normal idle speed (about 900 rpm) and stay there a few seconds then begin to drop again. If the engine is cold it will often die a couple times after starting even with the foot on the gas and then about the 2nd or 3rd time run with your foot on the gas.
At stop signs and red lights you have to keep your foot on the gas to keep it running. If you are approaching a stop sign and take your foot off the gas to coast to a stop and brake, the engine rpm will drop and the engine will die. It always starts fine though. Once you are driving it generally runs just fine at low or high speed. You can generally set the cruise control on the expressway and cruise right on. However, sometimes all of a sudden the truck will start bucking and jumping as if it has a terrible misfire. It usually lasts a few seconds and quits. Often if you step on the gas it quits. Even less occasionally the engine will begin to slow as if it is starved for fuel and slow down. You can press the pedal to the floor and it sputters a bit then picks up and runs fine.
I have read about all the threads in this forum and others and tried some of the suggested fixes but it still has the problem. I have tuned it up with new plugs, wires, fuel filter, air filter and PCV valve. Based on some of the forums advice I have replaced the IAC valve, the EGR valve and EGR Pressure Feedback Sensor, and cleaned and inspected the MAF sensor with MAF cleaner. I have checked all my vacuum lines and no leaks there and checked the engine timing which is fine. Fuel rail pressure and engine compression are also fine. Spark plugs show no clues, exhaust is clean and the engine uses virtually no oil. There has been no tear down on the engine like removing the heads, cam, timing gears or any of that and the engine is completely stock.
It shows no codes related to the problem. Two or three months after the problem started I showed a code that indicated an injector problem, traced the problem to a bad injector, replaced the faulty injector and it was fine. That took care of that code but didn't solve the idle problem. In my younger days I was into drag racing and I rebuilt engines, swapped transmissions, etc. and still do my own tune-ups today so I am fairly familiar with auto repair and have most of the tools for testing newer cars but this one stumps me. As a last resort I'm about to take it to the dealer.

My truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you don't rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat

My 2005 2.3l Ranger ran great. I moved a trailer about 150 feet and stalled the truck backing it up. Stick shift. Unhooked the trailer and pulled back into the parking area....all the sudden the truck has extremely rough idle and stalls. It runs good on the highway. AutoZone ran a OEM number to cross: P0171.
I cleaned the IAC with intake cleaner. No Luck
I unhooked battery for 15 min. No Luck
I sprayed intake with 1/2 can of intake cleaner. No Luck
I did not have a tamper torx to remove the MAF. What next.

So my 99 2.5 rcsb has been stalling out under loads, particularly when the A/C is on. It's stalled when warm, cold, engaging Drive or Reverse, and it steering does it at least once a day. There's a missing elbow to a vacuum line at the driver side (looks RABS related). The truck had the CAT melt off and now it's laying in my bed with the O2 sensor, don't know if that relates.
This truck sees 100 miles a day through the mountains, 5-7 days a week. It only has 140,000 miles on it, I put 40,000 on it in the last year with no issues. The truck is very much showing age (needs almost everything), but I'd like to keep the basics going.

I recently purchased a 1996 Ford Ranger with the 4 cyl. engine. The first 10 days I owned it it ran just fine. I then took a an hour drive to another city. After the first few stops there, as the temperature outside reached about 90, It started to sputter and idle very badly. After I got rolling it would would run fine. I decided to try to make it home. It ran fine at freeway speeds of about 70 mph. I had to stop once; it stalled out and would not start again. After waiting about ten minutes I tried again. It was still running rough, but I was able to get rolling and drove the rest of the way home without any problems until I was in town and had difficulty keeping it running at idle.
The next morning it ran fine again. A local mechanic changed the fuel filter, but the problem came back as soon as the temp neared 90 degrees. A mechanic friend who witnessed the problem said that it definitely sounded like a lack of fuel and not an electrical problem. Is there a way to troubleshoot without swapping parts? If the fuel pump is failing in warm weather, how is it possible that it runs fine at 70 mph, but not at idle? Engine temp gauge looks good. I did get one code after it died the first time (lean mixture, I think he said).

I have a 1999 B4000 V6 4.0L with 78K miles on it. I recently had P0171 and P0174 error codes come up. I replaced the MAF sensor and have not had the codes return but now the truck will basically stalls out when sitting at a stop light. It does not do it all the time just randomly. It has never done it when engine is cool but only once up to temp. The idle is smooth at cold engine but begins to get rougher once warmed up (nothing too bad just noticeable). I cleaned the IAC with MAF cleaner but no joy. I reseated all plug cables at the coil but no change. RPM around 600-700 then fluctuates up a bit then truck will stall quickly( I usually cannot put other foot on gas in time to get it to increase RPM before it dies)....

I have a 99 Ranger w/3.0. It idles about 1500 rpm cold,and 1200 warm. Here are the things that I have tried.
1.Checked ALL vacumn hoses/lines
2.Changed Air idle control sensor
3.Throttle position sensor
4.removed and completely cleaned throttle plate in throttle body.
5. removed top of intake manifold and checked for cracks and/or leaky gasket.
Nothing seems to change. Could it be a faulty ecm?

I've got a 99 Ranger. A month or so ago, it started to be a little hard to start. It would turn over, but not fully start unless I gave it a little gas. This did not happen all the time, primarily it happened after it had sat all day when I left work. Not long after that started, my check engine light came on. The codes were for a lean mix as reported from the 02 sensors. Before I could dig any further, it just wouldn't start at all one evening. This was after I had driven it for 30min and then parked it for an hour or less. But this time it was different in that the solenoid would just click, but that was it, like it didn't have enough power to turn over. I took the battery to have it tested and it had been severely discharged.
I got a new battery as that one had reached it's limits. Put it in and the truck started right up no problem. A few days later it started acting up again like it had originally, I had to give it some gas to get started. I had the alternator/starter checked, both were fine. A day later, it got so bad that I had to shift to N and keep giving it fuel anytime I stopped the truck. I had to do this all the way to and from work. Now this morning I go out and it starts right up, no issues, no dying at idle and didn't have bit of problem coming in. Initially we thought it must be a fuel pump, but then I can't explain why it worked fine this morning. I changed the fuel filter less than 2 years ago, so I wouldn't think it would require changing already. Wondering if there's a sensor issue, one that calls for appropriate amount of fuel?

I just got a 99 2.5 rwd auto and it shakes when it's at idle in gear. I'm pretty sure its because the AC pulley is engaging drawing power. I was thinking about turning the idle screw up a blonde-one because when I hold the brake and give it slight gas it goes away.

My truck is stuttering while idle and gets worse once it's in OD. My Check engine light is not on(yes it works). How to diagnose the problem. I don't know whether the plugs need changed, wires, fuel pump..

1999 mazda B4000 4WD 178000 miles 5 speed manual, I've been having a crank no start problem but after a few tries it would start, a week or so ago it was really cold (23) it wouldn't start so I opened the air box and shot it with starting fluid it took about 5 long sprays but it started.
It ran up op 3200 rpms and won't go back down, took it to my shade tree mech. he hooked it up to the diagnose thing it showed no codes, he poured water over the motor it different places and toward the back it idled down for a second so he says "blown intake gasket' so we replace upper and lower and sure enough we could see where there was a bad spot on the upper and a cleaner spot on the port.
That was not the problem it still idles at 3200, I mean wide open screaming, could the starting fluid have done something? Now he says "blown head gasket" I never had any idle problems before matter a fact besides the hard starting problem that started it was running just fine, what happened?

My manual 5 speed 99' 2WD 2.5L Ranger is starting to have some small problems here and there. My main concern is when I start the vehicle sometimes, there is no idle. The vehicle will turn over and if I do not hold the gas pedal down it will die immediately after about 2 seconds.
If I hold the gas down so the RPM's stay up (Around 700 RPM's or so, something just a little above 0 to keep it from dying) after about a minute, sometimes few minutes the idle will kick in and I do not need to hold my foot on the gas pedal to keep the truck from dying.
This is about all I know from the problem besides that it does not matter how long my truck is sitting. For example, my truck was sitting for 5 days and I came home and started it up just fine, but after I drove it a few minutes later and stopped driving, when I went to drive it about an hour later the symptoms came back again.
Also, My brakes are acting a little funny. I went through when I first got the vehicle and bled the brakes, took the front rotors in to auto zone or another shop and had them fixed up, and new brake pads. Sometimes when I first start driving the brakes are extremely sensitive, to the point where I apply a little bit of pressure and my truck will start skidding. This goes away after driving for a little bit though.

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.

I have a 99 Mazda b3000 v6 that has recently started to stall whenever in idle. Check engine light is on and the following codes popped up (P0176, P0135,P0141, and P0155). I'm sure one of these codes has to be related to the problem but I am clueless when it comes to troubleshooting. Also it started stalling after I filled up the tank. Not sure if that has anything to do with it, check engine light was already on before that.

My Ranger has been acting funny lately. My check engine light is on. I stopped by an Autozone and the guy read the codes - I don't remember exactly what the code was but he said I just needed to use some fuel cleaner - he recommended Seafoam. Now, I assume he was just trying to sell me something. But I've tried that, Gumout and STP in the tank with no luck.
If I'm driving and come to a stop, my RPM dips down to about 600 or lower, my truck starts shaking and will eventually stall if I don't step on the gas. This only happens with a warm engine - If I start the car up and go a mile down the road, it won't happens. But if I go 10 miles down the road, it will. I assumed I had a bad throttle position sensor so I just ordered the part and replaced it but the same behavior exists.
It's been a while since I've replaced the fuel filter - it might just be that.

1994 FORD RANGER stalls while driving - differant speeds ...differant miles ...no rhyme or reason to it - cranks right back up ...can even pop clutch and cut it back on. Already replaced Ignition Start Module - Dpes sensor - temp sensor - and scan shows all codes are clear and truck passes. We are clueless to whats causing this. 4 cyl 2.1

so I have a 1987 2.9L Ranger that likes to stall out when its idling after reaching temperature. Ive replaced all sorts of sensors (IAC, Coolant Temp, and PCV) and so far no luck. I was trying to figure out what the relearn procedure was for the IAC or get an input on any other possible sources of error. I haven't changed TPS yet.
What the engine does is when it gets up to temp, the engine will start to loose speed, and will start to shutter. Then it'll kick back up run fine for a few seconds and drop again, it'll do this for a few minutes then completely just choke out.

2003. Ranger xlt with the 4.0.... So I just bought this truck and was informed that the vacuum might not be functioning correctly. And here's the symptoms. It idles a little rough, nothing major. When I put the truck into gear either drive or reverse, it stalls out almost every time unless I give it some gas and hold the brake. But after that I could drive it all day with out a problem, as long as I don't put it into park. And last it starts a little hard. But the damn thing runs great while driving it. It's still very snappy even having high miles.

My 2003 ranger, 4.0l, 5 spd manual with 295K miles has no power on acceleration. Engine shutters/stalls. The following have been replaced in last 20k miles; fuel pump, plugs/wires, mass flow sensor and fuel filter. Last week left for work and could not go faster than 50 mph. Condition has gotten worse (barely goes past 40 mph).
Changed filter with no improvement.
Checked fuel pressure - constant at 65 psi.
Changed coil - no change.
The tank of gas I put in just before problem was from station with tanker dumping while I pumped. That tank is out of truck; filled from different station. Also put can of seafoam in tank. No change.

98 Mazda B4000 4.0 4x4
I bought this truck about two months ago and it has been great no problems starts right up and runs like a top. I was installing a 4 channel amp yesterday on and off and the dome light was on all day as the doors would periodically be opened or closed so it never did that cycle of 10 min or whatever when the lights turns off. This is what killed the battery.
I had my neighbor jump me and after a few minutes of charging it started right up and idled for about a minute long enough he left and parked, then it stalled. I started it about another 6 times before the battery died again. Every time it started fine then would idle between 1-10 sec then start to sputter and eventually die. Pressing the accelerator pedal only killed it faster.
I got a new battery today as the other charges so that I could fix it today without missing work again tomorrow. Unfortunately it does the same thing I was hoping that the voltage was just low or the polarity flipped or something on the other battery.
To sum it up the truck never gave previous symptoms just simply ran too low (battery never DIED the lights came on just clicked when starting) on power and now stalls when started which it does immediately no long cranking.
The twist; truck has an aftermarket alarm by Python. Problem is I don't know anything about the alarm or if it comes with an immobilizer. I am in the process of trying to figure this out but need to pull dash or something to find the "brain"? Never had an alarm like this I disconnected the clear square that adjusts the sensitivity hoping that was it but I don't know where or what I assume the brain of the alarm is.
