F Series :: 1982 F150 Truck Starts And Idles Just Fine But Stalls At Stops
Mar 9, 2015
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.

I'm having a bit of trouble with my fathers '03 Ranger Edge 4.0L. It has about 100k miles on it, and we keep it very well maintained. This is the first major problem we've had with it.
When the problem first occured, it had been driven about 30 miles on the highway and about 5 miles after getting off the highway, he pulled up to an intersection and stopped. As he started accelerating again, it all of a sudden started sputtering, surging (almost exactly as if it were running out of gas), and then stalled. It continues to exhibit this behavior. It will start and idle fine, but struggle and then stall when given any amount of throttle. It's also an automatic transmission if that makes any difference.
Fast forward to this past week after we had it towed home. We have checked the fuel pressure, and its dead on at about 64psi. We changed the fuel filter, changed the PCV valve, changed the upstream O2 sensor, put in a new air filter, cleaned the MAF sensor, and cleaned the intake of the throttle body. We're now at a loss as to what could be causing the problem. The CEL is not on, and there are no codes being shown when we plugged it in. We also thought it may have been bad gas, so we drained the tank and put fresh gas in from our preferred station. The plugs and wires are also fairly new, only about 4k miles on them.
Are we missing anything here? What else we could try? The absolute last resort is taking it to a shop, we're going through a rough patch with finances.

If I don't keep in the throttle immediately after start up it will stall a lot of the time. It doesn't do this every time or if it sits for a while but if I drive it and then stop off at a store or something and then go to start it back up it gives me this problem. I notice it idles about 3-4k RPM's when I stop at a light or something too.

I have a 1982 short-box chevy pick-up with a diesel 8 cylinder 6.2L that will start and run for a few seconds and then shuts down. It may restart and do the same thing. It will not keep running after an initial few seconds.
I have a mechanic that operates an automotive repair business in our hamlet and he took it on although not an expert on diesels. He works on it when he gets time and talking to him today he feels it must be an electrical problem shutting things down as fuel is getting from the fuel pump to the injection pump.

I have a 99 jimmy replaced rotary button, cap, plugs, wires. The truck doesn't seem to run right. It idles fine but when in load it starts to sputter a bit. Going down the road between 2000 and 2500 rpms the tach jumps a bit. Now if I put it to the floor the truck runs out fine.

Just recently my Prius Taxi with 340,000+Km has developed a little problem,it starts fine but after 20-30 seconds it begins to feel like it's not running properly on all four cylinders,if i go to the exhaust pipe it seems like it's spluttering slightly.
Yesterday I changed the plugs,checked air filter and all connections,everything fine, when I accelerate it feels hesitant but after the car gets up to temp it seems to go away,it only happens when i start it first thing or if it's been left for a few hours, it's never had the throttle body cleaned and I'm wondering if what I'm describing is a symptom of this?

1995 Mazda Protege1.5 LAuto153K miles.
My car was running fine, then one day it started sputtering while driving, mostly when I accelerated. It stalled and I could not get it started. This happened on a day when it was raining hard, but not sure that had anything to do with it. A few days later when I went to pick the car up it started right up, it had stopped raining and been dry for 2 days prior. But about a mile into the drive back home it stalled and I could not get it started.
Here is what I have tested so far.
- Put in new fuel filter.
- Tested the fuel pressure and pressure regulator
- Tested the injectors with a noid light.
- Tested that the spark plugs were producing a spark.
After I pulled the plugs and cleaned and dried them (they were wet with gas) the car started, but I think not because of anything really related to the plugs. What I've noticed is that when cranking the engine if I give it gas it will not start but if I keep off the throttle it will reluctantly start. But once it starts the idle is smooth and as it should be. Then if I give it any gas it immediately stalls. It seems to me given these symptoms that it is getting enough air to idle but not enough air to match the increased gas.
The only CEL code that I'm getting (which I had before this issue occurred) is the "closed throttle position switch" (I forget the number). If it was an MAF, or IAC, or EGR issue would I not get a code? What this could be and how to test it. Again my guess is its an air intake issue but not sure where.

I have a 2004 F-150 crewcab, 4.6L with 118,000. I don't drive the truck often but for the past few months its stalls and cuts off, and idles poorly in reverse. Truck cutting off at low RPM's, low speeds, and after going over some bumps. At one point the engine light came on but now it is off and I am still having the issues. . . . not sure what code it would display. I have been reading articles and blogs and most say the TPS, MAF, or IAC is the problem.

We have a 1999 f-150 just turned 200,000 miles. Two years ago replaced battery and alternator. Problem now sometimes starts fine, other times nothing. Can't jump it. Took battery out and had it tested and it is fine. Cleaned connectors. May start after thirty minutes, an hour, a day. Then runs fine for a few weeks or months, then problem returns. Have taken to two shops, but mechanics said couldn't find anything wrong bc of course it started fine at their shops! When wont start, Lights are on, but when try to crank, they go out and you hear nothing.

I have a 2002 Nissan Quest. It starts fine, idles great. But, when I try to accelerate, the car bogs, hesitates, misfires and I get p0300 random misfire, p0325 knock sensor. I get no dtc when it is just idling. The fuel pressure is fine, regulator works good, the cam sensor is clean, the coil tests good, the compression is good, as are the wires, cap and rotor.

I have a 2005 Ford F150. The engine sometimes quits when I slow down to stop for a stop sign or slow down to make a turn. I shift into neutral and it starts up and I am on my way again. This is an intermittent problem. Of course, it has never done this for a mechanic. It will happen 6 or 7 times in one day, and then won't fail for 2 or 3 days. The Ford dealership has replaced the air flow sensor. Did not work. They now think it is the throttle body that should be replaced. I am reluctant to replace this as they are not getting any codes from the computer telling them it is failing. They are not getting any codes related to this issue at all.

302 V8. Autolite 2150 carb. Auto-tranny. My vintage Ford truck which I love has developed a problem where it idles too fast for too long after warm-up. What I mean is that it is normal when it works correctly for it to idle fast for a few minutes until it warms up, at which point the idle speed slows down to normal. The way it works when it is working correctly, after a few minutes to warm up, I step on the gas pedal briefly, and the idle speed to kicks down. That's the way it is supposed to work. It seems actually like there are actually three idle speeds when it is working correctly. Fast, not quite as fast, and normal, all accessed via the kick down operation. Working correctly, it takes maybe three minutes to kick down the two steps to the normal idle speed. Does that sound right?
Anyway, the problem is that now it stays at the highest idle speed for 15 minutes. Eventually it kicks down to normal. But the high idle speed is too much for 15 minutes. Plus as it warms up the high idle speed becomes even higher since it doesn't kick down like it should. So it becomes difficult to keep the speed below 25 mph even w/out pressing on the gas pedal. It idles at about 25 mph for 15 minutes as it warms up!
I looked at my Chilton's manual -- better than nothing, but barely -- and it mentions something about a vacuum choke kickdown, a heat riser gadget, and the auto-choke. How to test each one to find what the problem is?

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 am working on my father's boss' 2004 Phaeton V8. The car usually sits on the weekends. What it is doing is, it will start and run smooth, but after 15 seconds, on the dot, it stalls and dies. It sounds like it is starving for fuel.
What I have done so far:
LH intake actuator arm found broken, replaced both with "Gruvenparts"
Checked all fuses and relays
LH fuel pump reads 14 volts until the relay kicks it off
Tested fuel pressure-good
Batteries fully charged
LH fuel pump reads 0.7 ohms w/key off
RH fuel pump reads 6.0 M-ohms when first connected and gradually climbs to 31.5 M-ohms
(I assumed this meant RH pump was bad and so I pulled it out and bench-tested. Ran perfect and tested at 0.7 ohms out of the car)
Re-assembled everything to pull the car out of the shop, and wouldn't you know it started and ran like normal.
Road-tested for 2 hours the next day without any problems.
So, I call the customer to pick it up and he says he will be there 2 days later.

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.

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.

its 1986 Ranger with a 2.9L V6 Auto 4x4, well to start with it seriously over fueling also it idles very roughly and even stalls out sometimes, when I'm trying to hold it at a speed it acts like it is missing (I guess that's from over fueling as well and it also pukes out lots of black smoke, it goes through way too much gas for a V6), but when I speed up fairly hard it acts fine until I try to maintain speed again, I have already put a tune up into it and a new EGR as well a fuel regulator and how to fix it?

I have a really nice 1986 Ranger XLT with a 2.9 V6 (injected) and OD Automatic with about 135k miles. I've had the truck for over ten years and have been pretty happy with it. I'm still trying to correct a couple of nuisance items:
1. Sometimes it runs smoothly, and at others it has a rough idle, and once in a while it will even stall. Before it stalls, it idles or runs roughly, and will miss erratically. When it quits, it does not fade out like it is running low on gas; it quits suddenly, like the ignition is turned off. If I am driving at highway speeds, sometimes it will buck as it misses, and sometimes stalls out. But it always starts up right away afterwards. This does not happen often, but when it does, it happens several times over hours or days, and then goes away by itself for months, even years, and then comes back for another round.
I was hoping whatever was wrong would totally fail, but it has been several years and is not getting better, nor worse. Fuel mileage varies, too, from 16 to high 20's MPG. I have new low- and high-pressure fuel pumps (dual tanks), new gas and air filters, checked all the electrical connections, put in a new ignition switch, new O2 sensor, Air Flow sensor, EGR, replaced all the vacuum lines, new battery and cables, new starter, all new electrical relays, fuel pressure regulators, new fuel pump inertia switch, tuned up engine (incl. wires, cap, rotor, ign module, plugs and timing), and cleaned out the already sparkling-clean tanks.
2. My oil pressure will drop at idle to low-normal when the engine is warm. It never goes to below Normal on the gauge. I have replaced the gauge, sending unit, and oil pump. This is a long-term issue, and is not getting any better or worse.

I have a 89 F150 4x4 lariat with the 302 8cyl and dual gas tanks. I was driving to work and the truck died. I have spark and enough juice to turn it over so I must be getting no fuel. When I turn the key to the on position I do not hear the fuel pump whine as it primes, it's dead silent. I'm assuming the fuel pump is dead.
Are there any fuses to check? I did check the switch that goes off when in an impact and it was not tripped off so it's not the problem.
My hayes manual (which i find is wrong ALOT) says that 87-89 f150's have a single fuel pump that is external to the tanks and found along the left frame rail? Can anyone confirm? Someone told me they thought it might have 2 pumps but I switched tanks and the truck still didn't start (or make a fuel pump sound) so unless the planets aligned and BOTH pumps blew simultaneously I would assume there's only 1 pump.

328i, inline 6, starts fine. drive 100 yards to stop sign, give the car gas to go, and it seems to stumble or stutter. gas has to be pressed heavily to get it to smooth out. seems to get better as the engine warms up. no code or engine light comes up. thought the engine was just cold natured, wife says it does it with her even when warm, I couldn't duplicate when warm. Can dealer diagnosis with no code?

I have a huge problem. My 94 ranger 2.3L 5 speed manual transmission, has problems with idoling while it's cold, has no power going uphill and stalls when I slow down to stop. This is all after putting a new motor in. The old one was running ok with 310,000 but lagging bad. I figured with the driving I do, a new motor wouldn't be a bad thing. Boy, was I wrong. It has been a nightmare. But once the truck is up to operating temperature, it runs so smooth you wouldn't think there was a problem. But let it cool off, restart, and boom! There it is. We have changed so many parts and sensors with absolutely no change to the original problem. It's very frustrating. I just can't let this problem win. I will figure it out.
