Ford F-150 - 1997-2003 :: 2000 - Idling And Running Rough On Acceleration - P0171 Code?
My daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?
Ford F-150 - 1997-2003 :: 1999 V8 Will Not Start / Truck Started Idling Very Rough And Died
1999 Ford F-150 V8 5.4L... The other day I was attempting to fix my 4wd. I discovered that the vacuum tube by the 4wd solenoid had become disconnected. I reconnected it and in an effort to see if my fix was successful, I drove my truck up one of the canyons nearby. I got to an area full of loose rock and popped my truck into 4wd. As soon as I began to drive, the truck started idling very rough and died. I attempted to restart it for the next few minutes unsuccessfully. I got it started once and it continued to idle rough for a few seconds and died. I have not been able to start it since. It turns over but will not crank. It is not throwing any error codes. What I have checked so far:
Spark plugs are working.
When turning the ignition into the ON position, I am able to hear the fuel pump working.
I have not seen any cracks in the vacuum hose.
All the fuses are still okay.
What the culprit may be?
Ford F-150 - 1997-2003 :: Idling Rough And Check Engine Light Came On After Running For About 20 Minutes
I replaced the heater core in my truck this weekend. The only thing I was worried about was pulling the dash. The truck is a 1998 f150 with the 5.4.. Everything went fairy well and decided to replace the AT Shift cable as well. Got everything put back. Truck runs, no leaks, no antifreeze smell. After running about 20 minutes, it started idling a little rough and my check engine light came on.
The codes are p0136, p0156, p1131, and p1151. I know these are related to the OS sensors. My question is could it be as simple as I miss an electrical connection when putting the dash back in? Was thinking possibly somewhere on the passenger side under the kick plate or possibly something while hooking up the heater hoses? Maybe even a ground that didn't get connected back when putting the das back in?
Ford F-150 - 1997-2003 :: Exhaust Leak Cause A P0171 Code / Idling Rough And Almost Stalling At Red Lights
It's been a long time since I have posted here mainly because my truck was wearing a bow tie for awhile. But my wife was nice enough to tell me the Bow Tie wearing truck was making a funny noise on New Years Day (seems a small drum corps took up residence in the oil pan). So anyhow now I am back in a real truck . My new to me 1998 F150 5.4 Liter ran fine until yesterday. It started idling rough and almost stalling at red lights. about halfway home the CEL light came on and is throwing a P0171 code.
So far I have checked for vacuum leaks including all the elbows on the PCV system' tried the spray test with a can of flammable break fluid and a can of starting fluid (man I love the smell of that stuff) could not find a leak. Cleaned the MAF sensor and the K&N air filter (not a fan of these) IAC seems to be working. Only thing I know that is leaking for sure is the driver side exhaust after the cat. But that is the wrong bank if I am correct on which bank is which.
So why only one bank running lean and why does it act like it is only firing on 4 cylinders?
Ford F-150 - 1997-2003 :: 2000 - Starting Rough Intermittently - Theft Light Flashes Once In A While?
I own a 2000 f-150 7700 series with a 4in body lift. recently Ive had a problem starting (I believe it is from the shifter not recognizing im in park) but now my theft light flashes at me and there is a weird sound that sounds like a relay from under my steering column when i roll my windows down, move shifter around or turn on 4x4. also my radio stays one every once in a while after the key is turned all the way back to off, and windows wont roll down after i hear the relay sound. Ive read to tighten shifter linkage and will do that tomorrow to see if that fixes it.

2001 with the 3.1 6cyl. First thing that started this nightmare is I was noticing a bit of a hiccup after driving for a couple miles. We've only had the car a few months and not sure what maintenance was done so we thought maybe it needed a tune up. Before I got the parts the check engine light came on so I went to parts store to get it read, it was P0302.
Did the wires and plugs and it got worse, the code wasn't p0302 now its just p0300. But after the plugs it also started idling really rough and would be slow to shift. Once it tacked up high and wasn't speeding up. That was only once tho. Also now it has no power its like driving a 2cyl ...
Anyway we decided since the first code said 2 we replaced coil 2, no luck..ok, fuel filter and fuel injector 2, no luck. Also has cleaned various things Im not sure of the technical name for..sensors and air filters and other things.
None of this has worked the car still idles very bad and doesn't have the power it should have. Also cleaned things on fuel rail(?). He is in the process of replacing the crank sensor as someone said if it was all the way bad it would throw a different code but it may just be faulty.
Toyota - Sienna :: 1999 - Started Idling Rough And Missing Intermittently?
My wife stopped for gas at a Circle K, about two days later this Sienna started idling rough and missing. I put some Seafoam in it and it cleared up. About one week later, she gets gas again, at another Circle k,about two blocks from the other one. Again, the next day she comes home from work complaining of the van running rough. I took it out and it drove fine. Whenever this happens the Check Engine light comes on, so I ran a code reader on it and it tells me, "Miss detected on cylinder 3".
So I checked all the plug wires, took out the plug (which I had just changed back in Oct.) and checked it, it looked fine. I thought maybe it could be the coil, so I switched the coil to see if I got the same code reading on a different cylinder. I unhooked the battery to clear the code after switching the coils, started it up and still got the rough idle and code. I turned it off (the van) and go in the house, I come back out and start it and it's running fine. I go to the store and all is well, go inside the store for maybe 45 minutes, come back out and start it up, I get the rough idle and missing.
I ran the code reader on it again and cleared the code, then restarted it and it was running fine again. Whatever it is, it has something to do with starting the engine (a 3.1L). One time it will start up and drive fine, the next time it starts the rough idling and missing. I figured if it was the coil and I switched them and got the same code on a different cylinder I'd narrow it down, but so far it has been running normally.
Volvo - 850 :: 1997 Started Stalling Intermittently When Idling
I have a 1997 volvo 850 that has started intermittently stalling. It usually happens when i'm idling, like at a stop sign or traffic light, but recently it did it on the freeway. I have taken it 6 times to the mechanic (5 times to one and finally having learned my lesson the last time to a new one) and they say it is one of 4 things, but can't figure out which of those 4 things it is until it stalls on them. which it hasn't done. it acts perfectly when at the mechanic's and then they always give it back to me, only for it to happen again. the last time the car ran beautifully for 6 weeks before stalling out on me again....... oh, and once they replaced my fuel pump which seemed to work for a while.

I'm having trouble with my Taurus 2003 and the mechanic is struggling to find anything wrong;When idling, if I turn on the A/C on the car will start to shudder intermittently. It feels kinda like an engine misfire...The mechanic replaced the spark plugs and the trouble seemed to disappear but was back again after a number of weeks. When I took the car back the oil-seal was leaking so I got those replaced. It may possibly have been better for a few days [It's a bit difficult to gauge as the problem is somewhat intermittent] but then the problem was back.

I have a 99 f450 with a 7.3. Here lately it has been "missing" when driving or idling, but only every now and then. When driving down the road it will start bucking and boiling black smoke out then the ses light will come on and like turning a switch everything clears up and it acts and drives normal.
View 11 RepliesFord Super Duty (1999-2016) :: 1997 F450 Idling Rough / Died And Would Restart But Has Zero Power
It has 100k on the clock. I bought it about 2 years ago and only put about 500 miles on it. It is only used as a farm truck. Historically it would periodically die at idle in park. Would always start up immediately and run fine. Plenty of power.
Today the truck started up and idled a few seconds and started idling rough. It died and would restart but has zero power. Put it in gear and it would die. Did this a few times now can't even get it started.
I checked all fuses. I checked the dist cap and rotor. Don't look the best but don't think this is the problem. I get the same result on both front and rear tanks. From what I have read sounds like a fuel pump or regulator. Where is the regulator located?

Ford - Explorer :: 2003 - Idling Rough With P2196 And P0174 Codes
I've got an '03 Explorer with the 4.0L SOHC that I got for a deal on craigslist as it needed timing chain tensioners. I got that all done and it runs and drives relatively well, but it idles a little bit rough - especially when it's sitting in gear at a stop light. My go-to first attempt for idling issues is to squirt off the MAF sensor, throttle body, and squirt some starter fluid around the vacuum lines to check for vacuum leaks (though it's possible I may have missed a line or two). Neither seemed to work much. I cleared the codes, dumped some Sea Foam and fresh fuel in it and drove it around a little bit and it threw the CEL light, got about 10 mpg, and generally just didn't seem to have as much power as it should (though I have no experience with the 4.0 in a explorer, soI'm not counting that as a hard fact).
I pulled the codes and I've got a:
P2196 (O2 sensor stuck rich - bank 1 sensor 1)
(and)
P0174 (system too lean - bank 2)
That seems kinda weird to me. Bank 1 is rich and bank 2 is lean? That would make it idle and run weird, for sure, but I'm having a bit of a hard time figuring out what would cause that. I think my next step would be to check/replace the plugs, but that's more of a shot in the dark than a proper diagnosis.

My 1997 f150 5.4 has started an idle issue. The truck when started will idle around1200 rpm and not settle down After driving a bit it will drop down around 800 and idle rough and sounds like it has a plug fouled. As soon as you give it gas it clears up and sounds fine, then drops down an idles rough.
Checked for vacuum leaks but don't see any. pulled the MAP sensor and cleaned it, but did not change.

On cold and/or wet days weak engine cranking. After a couple of attempts to start, I only hear a click about the 3rd attempt. If I wait about a minute or two, it still cranks slow but starts. Battery was replaced about 6 months ago. Electrical systems test good indicating no problem with battery, altenator, or starter. I don't seem to have any problem on warm days. My car is 4-cyl with about 85,000 miles and is kept in an unheated garage. Mechanic thinks trouble is likely the starter. Problem is intermittent, I'm not sure replacing the starter will fix the problem.

I have a 97 F150 with a 4.2. It has started to surge or stall out when I slow down sometimes. It doesn't do this all the time. I replaced the fuel filter about 2 mths ago and replaced the fuel pressure regulator then also. Would the tps have anything to do with it? I haven't had a scan done yet. Thought I would try here first because at one time someone has removed the two cats and the check engine is on all the time.
