Ford Ranger / B-Series :: 1986 - Stalls / Idles Or Runs Roughly And Will Miss Erratically

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.

Ford Ranger / B-Series :: 1999 - Hesitates To Start And Won't Run In Morning?

I have a 1999 Ford Ranger and every morning when I go out to start it, it really hesitates and doesn't want to run for a few minutes. once it's going it's fine I can shut it right off and it starts fine, and I can leave it all day from 9am to 6pm and start it again at 6pm and it doesn't hesitate, it fires right up.. it seems like it only happens over night..

When I hooked the code reader up, I get codes P0171 (too lean bank one) & P0174 (too lean bank two)

I also get for the I/M readiness status, that the

EVAP - NOT RDY,
O2S - NOT RDY,
HO2S - NOT RDY

Just want to say also that the shop I had put 2 oxygen sensors in not long ago.=

Ford Ranger / B-Series :: 1991 - How To Time Idles High At Start

I now have a 1991 ranger 3.0 super cab. I need a step by step walkthrough of how to time it. Keep in mind that I ha the distributor out while turning the engine over so I need from start to finish, including the spout connector. It runs right now but idles high at the start and the. Stumbles down to about 500rpm and sometimes dies....

Ford Ranger / B-Series :: 1986 - Start Over Fuel - Idles Very Roughly - Stalls Out?

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?

Ford Ranger / B-Series :: 1999 - Rough Idles When Started / Have To Hold The Gas Till It Warms Up

Quick back story I bought a 1999 Ford Ranger It is a 4 cyl with an auto trans the guy said it had some trouble with the tranny (major understatement) he also forgot to mention he cut out the CAT. so running a 4 banger off the header.

When you start the truck it rough idles but you have to hold the gas down til it warms up. You can shift into reverse but it labors the motor and the motor will not up the rpms kinda stays at idle and wants to die no matter how hard you accelerate and you can't move up a slight incline.

When you shift into drive you have to rev the motor to 3 grand an it will catch then move slowly forward. no matter how high the revs go. The fluid levels are a tad above the full level and a bit dark for my liking.

Ok, I used an OBDII scan tool from the parts store and it came up with 3 codes P0351, P0352, P0500. From my internet search the first two seem to be coil related which explains why the motor is running like garbage. The last may or may not have to do with what the tranny is doing.

Golf IV / Jetta IV :: Hard To Start In The Morning / Sometimes Idles At 500 Or Lower

So the car is a 1999 golf gti with a 2.0 AEG with a 5 speed manual. My brothers car. He has been telling me its been hard starting in the mornings for a couple months, sometimes it dies, sometimes it idles at 500 or lower, he has to rev it up to 1500 to get it to warm up then in kinda stays normal till he cold starts the car again, then does it all over. So he was driving down to my house to leave it with me to look at and on the way over he heres a big bang. has the car towed over here.

Cyl #3 has backed itself out and clearly a serious misfire, threads look fine so I put all new plugs in oem ngk three prong, runs ok still too low 400/600 stalling a couple times. this morning i installed new wires (Bosch)and a coil (aftermarket) and it barely wants to run now, stalled instantly. So I put the old coil back in and it stays running but watching the motor, its clearly misfiring. No codes as of yet and i have no access to vagcom. I've checked the firing order and wire placement on coil like 8 times to make sure it is correct.

Ford Ranger / B-Series :: Idles Like Crap Up And Down With A/C On Or Off And Eventually Die

96 Ranger 2.3 5 speed, 2wd. 212k on the clock.

Bought this from my BIL last week. CEL was on so I ran the codes. replaced the air filter, cleaned the MAF (with CRC MAS cleaner), replaced the EGR solenoid (physically broken). The first code showed this was throwing the code. That code (p1409) went away but p0402 showed it's head. replaced the DPFE sensor, disconnected the battery for an hour and am now code free.

Now it idles like crap, up and down with A/C on or off to nearly dying and does eventually die. Disconnected the MAS and no change. Cleaned the AIC no change, replaced the AIC with no luck. Checked for any obvious vacuum leaks around items I messed with. Found nothing. With engine running I disconnected the vacuum to the EGR valve and idle smooths out. Feel a small vacuum tug from the hose, nothing at the valve.

Haven't changed the PCV or cleaned the throttle body. Could it be the EGR valve since removing the vacuum seemed to work?

Side note, BIL's mechanic told him THREE YEARS AGO the CEL was 'probably a O2 sensor' and that is doesn't do anything and no need to fix.

Still no codes and still no power. Can't hear any vacuum leaks. Bought new plugs and wires but haven't installed them yet. EGR? TPS?

Ford Ranger / B-Series :: 1996 2.3L 5 Speed Idles Too High

My son just purchased a 1996 Ford Ranger 2.3l 5 speed it is a nice little truck. But I have a question when you press in the clutch it acts like the choke has come on it idles way to high. When you come to a complete stop it is a few minutes before it goes back to its regular idle. Is it suppose to do that?

Ford Ranger / B-Series :: 2003 4.0L Idles Fine But Stalls When Given Gas

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.

Ford - Escape :: 2006 - Lacking Normal Power - Slow To Start

I have a 2006 Ford Escape Hybrid with about 150,000 miles.

It sometimes is lacking normal power - slow to start but fine once to full speed. When it is lacking power I notice that the gas engine is not shutting off when stopped at traffic signal like it normally does with charged batteries. It will be like this or a few days and then suddenly has its normal power and shuts of at traffic signals again.

Seems to be some failure of communication in the hybrid controls with system not telling the electric motor to do its thing. Where I should start looking for fix of this intermittent problem?

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Feels Like Power Lacking?

00' 7.3 is acting a little strange lately. i was towing a 15 foot trailer the other day for about 250 miles that wasn't all that heavy and my foot felt like it was very close to the floor. I had it to the floor and the truck would only go 60. now even without that trailer its better but still i feel as if i have to really put my foot down into it to speed up. if i go all the way to the floor in o/d it'll downshift and start speeding up but very very slowly then i run out of pedal and am at the floor, a lot slower than before. Before i wouldn't get to the floor and id already be moving pretty good. but now i gotta keep it pretty much 3/4 way down and keep it there to get up to speed and stay there. truck has 253k no tuner or programmer just 6637 intake and an exhaust, ww2. leveled on 35's. the tranny isn't slipping or at least doesn't seem to be. She doesn't shift perfect but its not anything crazy bad for stock with 253k on it. maybe something wrong with the actual pedal? or hopefully not but maybe the trans or motor , or maybe a sensor or something?

Ford 7.3L Power Stroke (1999-2003) :: Harder To Start In Morning

Replaced cups 3ish years ago
Replaced IPR (non- Motorcraft) and ICP last year
New (not remans) PIS Stage 1 injectors with Hydra Flash October

Truck has been running and starting (down to 19 degrees) like a dream since the new injectors. After the last fill up the truck has been harder to start in the morning and if I don't let it warm up till at least until the needle moves it will stall and be difficult to start. Once started and up to temp it runs just fine but will definitely take aa few extra turns to get started whether cold or hot.

There is CEL, I don't smell or see any diesel in the coolant, oil looks good and the diesel in the filter is kind of a clear blue? The way it acts when it stalls is kind of like when the IPR went bad the first time... kind of. The few times I was able to get my phone connected fast enough I saw and IPR duty cycle in the 90s flash and a HPOP pressure of 1500 or so flash all while the truck is barely hanging on to an idle.

Ford Ranger / B-Series :: Engine Idles Oddly - Slows And Speeds Back Up When Stopped

96 Ranger x cab 4.0 ltr automatic... Starts fine, runs fine until I stop.

When I stop, the engine idles oddly - it slows and speeds back up, tachometer and the battery gauges both lower just a bit and immediately return to normal. When the headlights are on, they dim in rhythm when the gauges dip. It does not do this in park or neutral.

Sometimes it does it right away. Sometimes it doesn't do this at all. Of course it did not do this when I took it to the shop. The battery is nearly new. Cables are fine. Alternator checked out ok.

Ford Ranger / B-Series :: 1994 V6 Idles Low - Surges Up / Down - Black Smoke Puffs And Smells Like Gas

I have a 1994 Ford Ranger with 4.0 V6 Automatic. The problem is when it idles it idles low and surges up/down and pushes a very small amount of black smoke puffs and smells like gas. I have installed new coil, new wires, new plugs, new ect, new crankshaft position sensor, and new maf. It has new intake manifold, new injectors, new alternator and it still does the exact same thing. Nothing is phasing it. I ran the key on/engine off test and got egr codes and a map sensor code, then ran the engine running test and got 998 and 126 code. The 998 code says that its basically a hard fault/ have no idea.

I do know this is a donor engine out of another year not sure what year, but i know when i ordered the coolant temp sensor the only ones that would plug into it are the years 1990-1993. Now here's my other question, why would the computer give me a map sensor code when truck doesn't have a map sensor? It has MAF sensor, and why egr codes? The truck doesn't have egr and never came with it. I do know I've unhooked battery and replaced the maf and its like it doesn't even recognize it? Could it be the ecm/computer bad or needs flashed?
