Ford - Explorer :: 1998 - Stutters When Idles / Gasoline Smell When Push Gas Pedal
I have a hesitation/stalling issue with my explorer. Started about 2 months ago and can't figure it out. It began with truck feeling like gas wasn't getting to it and it was kicking as if it were getting it, but not at the right times. Asked around was told the throttle body positioner may be going bad as well as fuel filter might be getting clogged. Replaced both and it seemed like it worked as it felt like it was driving ok, but it was all in town driving. Took to interstate and began kicking again. Then, it started to misfire?? or lose power in town and would stall at lights and or turns. Talked to some other people and said it might be my Intake air control valve and or gaskets are leaking from the upper/lower intake.
I got new IAC and got new gaskets and cleaned lower intake and changed oil as well. It ran great for about a day or 2. Got it on HWY and around town and it was great. Now runs absolutely horrible. Feels like it stutters when it idles and when I push gas pedal I get the smell of gas and it wants to die. When pulling off upper lower intake unnoticed that the long screw to upper intake weren't all the way down in the back. I made sure to bolt them down tightly. I was told today to try and reset the computer by detaching the negative battery cable and using a wire to attach that detached cable to the power cable. Then to reattach, turn key to get accessories going for 10 sec, start and idle for te min, turn on lights for about 1 min, followed by radio and then ac. Then test drive for 10min or so. This may have made it worse??
I'm not a mechanic by any means but believe I hooked up everything correctly as it ran great for a day or 2. Also, a bit back I had P0107 bank one lean code pulled up. No engine light has ever come on. Have not had it rescanned since I replaced IAC and gaskets. Just don't know where to turn next. I also cleaned MAF, put in new air filter. 1998 explorer 4.0 SOHC....
Ford Super Duty (1999-2016) :: 2011 F250 - Engine Idles Rough Until Warms Or Accelerator Is Pressed Down
On a cold crank the engine idles rough until it warms or the accelerator is pressed down. Also runs rough going up hills or towing. Check engine light is on and is throwing the code for bank 1 to lean and cat performance below threshold. Cats have been tested, good. Fuel trim tested, good. One mechanic said noth8ng is wrong with it well, there is. 2011 f250 6.2 gas...

ok so let me start by saying, my name is Tim, I own a 1999 Ford Ranger 6 cyl, 3.0L truck, I bought it brand new in 1999 and drove it for a few years and then took it off the road for 3-4 years then last year I went to put it back on the road and I couldn't get it running.
I took it to the dealer and they replaced a key switch module. since then the ranger seems to lack power. It also idles erratically when you first start it in the morning too.
not sure whats going on here but the engine light is on,
I get codes P0171 & P0174 (too lean bank 1 and too lean bank 2)
I would also like to note that I have replaced the fuel pump, fuel filter, transmission filter, MAF sensor, IAT sensor, PCV valve, EGR valve, TPS sensor, idle control solenoid, fuel pressure regulator & new plugs. I have also checked for vacuum leaks with no avail.
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 - 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.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Idles Fine But Runs Rough After Warms Up A Little
2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.
I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.
I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.
Ford - Explorer :: 1999 V6 Noisy And Idle Will Decrease After It Warms Up
Since we bought this car, it has had an issue where, after it warms up, it begins making a noise which I've seen described as "moosing" on the internet. In addition to the sound, the idle will decrease and will sometimes kill the engine.
I've seen this attributed to the IAC, and so I replaced it (twice). I have tested the IAC connections as well, and all is good. I have even run the car without the IAC plugged in, to try to reset the computer, to no avail. I feel like I have eliminated the IAC from being the problem (but maybe not.)
I have replaced the PCV valve.
I have replaced the water temp sensor and the thermostat (someone suggested this might affect the computer and rpms...)
I have cleaned the MAF and tested it per the Chilton's manual. (tested fine)
I suspect that because of the idle and the engine seeming to be choking out when it dies, that there is a vacuum issue somewhere. I just don't know where to start with this.
Ford - Explorer :: 1998 - Engine Swap - Sensor Interchange?
What is the difference between the 2 wire & 3 wire cam sensors. I am installing a 98 4.0 in my nephews Explorer-engine build date of 12/98. The replacement engine build date of 5/98. There have been quite a few differences during this process and thought I had them worked out but the old engine had a 3 wire cam sensor and the replacement has a 2 wire. I have already changed the harness over due to other differences but my main question is will I have to swap the synchronizer or will the sensors interchange? The synchronizes look different as does the cam sensor.

I have a 1999 Ford Explorer that when it starts in the morning sounds like a tractor and stalls out till it warms up after 5-10 minutes. This is of course wasting gas and I've replaced spark plugs and wires and 2 oxygen sensors. After the truck warms up it runs fine but it's very frustrating in the morning and good that I have a strong battery-check engine light is on-what could be the problem?
View 2 RepliesFord - Explorer - Transmissions :: 1998 - Engine Surges At Constant 2500 RPM
I have a 98 ford Explorer that has some serious trans problems. It all started a while back when I was pulling a small 10 foot trailer and when I go to where I was going the trans puked out what looked like all of its internal fluids. It was a hot day, and these problems seem to be exacerbated by the heat but who knows. Yes the check engine light is on. I also have the occasional O/D OFF light blinking at me. As of late the vehicle has started to act like it has a stall converter on it. I have to rev to nearly 3k RPM before it will engage.
I changed the fluid and filter about 2 months ago and the fluid is already grey and nasty. The vehicle has also started going FORWARD in ALL gears, Reverse, Neutral, etc. all are forward gears now. The trans occasionally overheats and pukes out a large amount of fluid but I cannot tell where it is coming from. At road speed (55 MPH) the engine surges when it is at a constant 2500 RPM. I know my outlook is grim but if I just need a new torque converter I would like to know before I go the the Salvage yard for a different transmission. BTW. The engine WAS replaced around 12,000 miles ago with a donor engine from a flipped vehicle.
Ford - Explorer :: 1998 - Sputtering Sound Coming From Lower Part Of Engine Compartment
I just got a new clutch and clutch slave cylinder in my 1998 Ford Explorer. Driving it home from the mechanic, I'm hearing a sputtering sound coming from what seems to be the lower part of the engine compartment. It sounds like a VW Bug exhaust. I've never heard this sound before. It's troubling that it has appeared now immediately following a repair. I presume there is a outside possibility that it's not the mechanics doing, but that seems improbable. (The engine was revving high right before the clutch blew out last week, so maybe those brief high revs caused some damage? I can't imagine that being the case.) Or was there something in the clutch repair process that could have resulted in this?
I made a recording of the sound here.......
Ford Excursion :: Engine Knocks Badly / Revs Erratically And All Gauges Not Working
The other day I bought an sct tuner for my excursion and its been a little glitchy, likes to freeze up and lock out my ecu.
I was driving yesterday and today I try to turn it on and my engine knocks badly revs erratically and all gauges weren't working so i shut it off. I tried to start up again and it flashes the theft light and abs light. Won't crank won't do anything my whole engine is locked out.
So i tried reverting the ecu back to stock. I did this several times once it simply lost power and shut off at the end another time it said wrong vehicle and the final time it said completed.
Now when i try to start up it does the same thing and will not do anything but flash lights at me... When I downloaded the file it said select vehicle: 6.0 superduty. That was the only choice, and the guy at the store said that the truck tuner will work in my excursion I specifically asked if this works in the ex.
I really need my truck otherwise I will he paying hundreds in taxi fare. I tried calling the store and sct but both are closed on weekends.
Explorer :: 1998 - No Engine Braking In 4x4 Low
1998 Explorer 4x4 4L
The drive train freewheels when going down hill in 4x4 Low, and 1st gear. Shouldn't the engine be braking the vehicle when in 4x4 Low, and in 1st gear? It is free wheeling which is very hard on the brakes; I had to ride the brakes the whole 2 miles down (a lot 45 degree grade).
Ford - Escort :: 1998 - Run For About 15 - 30 Seconds Then Slowly Idles Down And Dies
Iv got this escort from my sister, i assume it has been hardly maintained considering the... state. I bought it because she was tired of dealing with the problem... driving, it will turn off. She said it got to the point where she just stopped driving it, although it only happened twice. It began when first time it shuttered then died. Took air filter off and it only ran it like that to get it home. Now it doesn't run but for a few seconds even without air filter, so Its the best choice to leave in.
Anyway, I've replaced:
-PCV Valve
-Fuel Filter
-Some dry-rotted hoses
-I didn't replace it, but i cleaned throttle body and MAF sensor in the intake.
I've tested alternator and batter, both are good. I tried fuel treatment. Being honest this is the extent of my.. automotive understanding. But Im fairly certain it is a fuel system problem.

Ford - Explorer :: 2007 - Hard Start - Idles A Little Rough
After sitting engine cranks longer than it usually did before it starts. idles a little rough. engine light comes on after it been running about 30 sec for 1 min. after that seems to run fine.check codes po446 and p1633 always come up. if you let sit a bit with key on starts right up.replaced gas cap checked evap lines, and changed filter no luck. Did notice with lines off evap solenoid key off or on i can blow through it. that doesn't sound right.
Checked fuel pressure. key on jumps to 90psi then falls to 55psi and stays. turn off key and leaked off 10psi in 5 min.start engine while watching gauge does the same as when the key on except it falls to 30 to 35 psi and bounces between them. i think this is way low. What is the correct pressure? Shut off engine and drops to 20 in 5 min. Next I plugged line on test tee going to fuel rail and tested same results as key on. the convinced fuel pump was bad since regulator and check is there. replaced pump. problem still there.
Touareg :: Starts To Idle Erratically - VW Engine
My Treg starts to idle erratically. It feel as if it want to stall once every 30 seconds. Other than that it drives great. I talked to the dealer and they said that this is typical of VW's engine. It does not make sense. I did not experienced this when I first bought the car.
View 7 RepliesNissan - Maxima :: 1998 - Runs Rough Once It Warms Up - Doesn't Idle Well
My 98 Maxima won't idle without dying, it sputters when you accelerate, and it tries to die while coasting. I've changed two O2 sensors (AutoZone gave me the code for bank 1 sensor 1 & 2) changed spark plugs, tried fuel injector cleaner, oil change, and cleaned MAF sensor & checked the wiring. It;s still spitting out the black exhaust. Although after changing the O2 sensors it quit for about a day or two but started again (I'm guessing the other sensors need to be changed to) But the main problem is once it warms up, it really runs like crap, and is a major gas hog. I'm getting about 12 Mpg.
