Ford F-150 (2004-2008) :: Shut Down To Idle / Wrench Light Came On - Code P2104
Well, truck did it again last night. Shut down to idle, wrench light came on. My Edge Insight showed P2104, Throttle Actuator Control System-Forced Idle. This is the third time it's done it over several months. Took it to Ford again, they didn't find anything. First time they replaced the throttle control unit. He's talking about RF interference but ignition & alternator checked ok. Each time it's done it has been in the same place, Sacramento Raceway. This is getting ridiculous, can't just drive it & show them because it's only done it over several months period.

I have a weird intermittent problem. Sometimes when I start my explorer it will idle down and die immediately, I restart and it will idle about 400-600 really rough, sounds like it is missing. When I drive it it is jerky and the acceleration is sluggish but after I get it up to about 20 mph it clears out and then drives and idles fine until I shut it down. Plus these things only happen about every third time (on average) that I drive it. Lastly it's not giving me any codes. What this could be?

I love my Ranger. I'm quite impressed with the power and durability. I'm ticked at Ford for stopping production.
I have searched my problem and could not quite narrow it down. I have also tried several remedies with no improvement. I need to narrow it down to a specific item.
2004 Ranger, 4.0 liter, 4x4, 131,000 miles, runs great above idle.
Problem: rough idle, idles at about 750 rpm's. If i raise the rpm's to 850 and up, smooth as silk.
The truck did this a few years back. Not quite as rough and it went away by itself.
Engine light came on this time with P0303 & P0316 codes. I have replaced: plugs, wires, coil pack. I know that the #3 plug is sparking quite well. the #3 injector is getting signal to spray not sure if it is. I have 4 O2 sensors and I believe I tested them correctly (passed). The passenger side upstream or pre cat sensor has not been tested yet. Had to rent a tool and will do that in morning. I slid a piece of aluminum roof flashing between the crank position sensor and the crank pulley. Not a noticeable difference. While at idle (750 rpm's) I pulled each (#3,2,1,) (one at a time) injector wire plugs off the injectors. No noticeable difference. I pulled the vacuum line off the egg and operated it with a vacuum tool. Seems to be working fine. Sprayed carb cleaner around on vac lines. No engine surge
Ford F-150 (2004-2008) :: Rough Idle / P0012 - Misfire Codes Associated With Bank 1 And Cylinder 3
5.4 3v. my last few weeks have not made me a fan. Here are the details:
I bought a 2008 F150 XL 5.4 3v with a cam phaser knock. Have done other timing jobs in past with no trouble so I was not too afraid to tackle this one. famous last words...opened the motor (shout out to the passenger side valve cover and its designer here) and found semi damaged roller follower on driver side. Worn cam lobe on the corresponding lobe and a loose chain on passenger side. proceeded to :
Change all timing components: phasers, chains, tensioners crank sprocket, all applicable bolts and BOTH cams as well as all lash adjusters and roller followers. most looked fine in fact all really did with a bit of wear on a few roller followers but only one bad one. engine didn't look to bad pretty clean.
Double and triple checked my timing chains and it was spot on. dark link on spot on crank, two dark links on the L and R dead on. put it back together. oh yes, changed all plugs with motorcraft ones, didn't even break one. did not change vct solenoids because I falsely assumed I could change the later easily if needed. they looked ok. screens intact etc... silly me for not realizing how kind Ford was in 2007 and later to necessitate removal of valve cover. I was reading a previous one on the how tos and assumed later models would be the same since it was the same sensor...
Cranked truck ran great. I mean perfect. sounded perfect. ran like a scalded cat. till it got to hot idle then it started doing its thing. rattle shake till you revved it. ran fine just wouldn't hot idle fine especially in reverse or under slight load. replaced driver side vct since ford only had one and I started on the easy side ordered the other one waiting for it. seemed to improve dramatically meanwhile I am driving this truck to test it. I drove it to work 50 miles each way and it ran great.
After a few trips it popped the P0420 light, seemed to run ok, cleared it watched it wouldn't come back. O2 sensor did seem to imply a bad cat on bank 1 since it seemed sensor two was mimicking sensor one and not staying stead like the other bank. still ran fine,
So I decided to check back pressure on the cat. I pulled sensor one out of bank one (really a joyously tight squeeze in there) hooked up my gauge and got 0 back pressure. revved it and all nothing. hooked sensor back up pulled truck out of shop and it commenced to running like crap. I mean bad. running worse than before I got it. Popping P0012 code continuously, and tons of misfire codes associated with bank 1 ..cyl 3 etc.. I tried swapping coils, pulled coils and checked spark with a tester and firing away looks like tons of good spark.
Now the weird part is : looks like bank one is dead. I can unhook any coil pack and/or injector and it runs the same and sounds like it is missing. if I unhook one off of bank 2 it almost dies or does. so bank 2 seems to be running fine. it will start and run but sounds like it missing sets flashing check engine light and backfires and stalls like crazy. I even second guessed my pressure gauge and unhooked exhaust manifold from pipe and it sounds even prettier when it backfires out of there but no change. I pulled cam sensors and cleaned it again and even tried swapping them since they looked identical but no change so I put them back.
Now I can only surmise that I am out of time somehow? or I have a gremlin perhaps? I like working on cars (usually) but this one is getting old. how do I verify what is wrong. if it is timing related how do I verify that now definitively once my marks moved I really cant figure out how to tell if it is in time? Since it has all new parts and they all ran beautifully till now. could it possibly be the vct solenoid doing all this? I plan on changing it when it comes in but surely it cant cause this many problems.. I unhooked it no change, and it does it at a cold idle and any rpm. really runs worse at idle but bad at any rpm.
Ford F-150 (2004-2008) :: Misfiring - Rough Idle - Got Codes P0340 / P0344 / P0345 And P0349?
I recently purchased a Ford pickup. I bought a 2004 F-150 with the 5.4L 3V engine. I have only driven it for about 300 miles so far and am having problems. The engine has 200,000 miles on it. I have read several posts on here about the cam phasers which I believe that I may have some issues with. The engine will run good when cold, on the road, etc. The engine does have a slight ticking after it warms up (cam phasers?). When I come to a stop after the engine is operating temperature, the engine will start to miss and shudder and all 4 above codes come active and are also pending (8 codes in total).
All 4 codes are logged at the same time. I have replaced both cam position sensors, both sensor ends and terminals for cam position sensors, checked wiring around rear of engine (does not appear to be rubbed through), all plugs were replaced, and all COP boots are good. Is there anything that can cause these codes that may not be the actual cam position sensors, ie. VTC, COPs, cam phasers? What pins the cam position sensors come to on the ECU (so I can ohm the entire wire harness)?
Also, if the engine is missing with the codes active and I rev the engine up it will come back to idle and run great. The engine never dies out, just runs horribly. I have also unplugged each sensor with the engine running which has no effect on the way it runs.

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.
Ford - Explorer :: Rough Idle At Start Up - CEL On
When I start the truck it hard to start and the idle is rough but when it warms up it seems to get better but still miss fires now and then so i was thinking could it be a bad O2 there is now "CEL" because the battery was dead (installed a new one) and the truck has not been on the road yet (want to get everything fixed first) and update on the door alarm will be working on that tomorrow almost forgot 2002 explorer 4.0L "E" for the vin 4 wheel drive 124k on it.
View 5 RepliesFord - Explorer :: 1995 - Idle And Acceleration Rough
I have some major problems with my explorer. The idle is rough and accelerating is rough also. If I nearly put it to the floor it almost seems like it studders the power. it will feel great for a second that feels like it's less power for a second then more and less and more and less. When I'm sitting at idle, it will idle fine then after a minute or so it will bog way down and shake the whole vehicle. when that happens I give it some gas and it comes back to normal idle then it does it again after sitting for another minute. I've replaced spark plugs, wires, alternator, oil change and some tires. I've been told by many mechanics it could be the IAC Valve or the fuel pump or the fuel filter or a vacuum leak.
View 8 RepliesFord - Explorer :: Running Rough When Takeoff From Idle Until Hit 25 - 30 MPH
My explorer has been running a little rough, particularly at idle. When I take off from a rough idle, it'll run rough until I hit 25-30mph. I ran by O'Reilly's hoping to pick up a pack of spark plugs and be done with it, ended up leaving with a new MAF sensor. It ran better for about 10 miles (I'm a delivery driver, so I did a lot of stop and go immediately), before it ran even worse than it did before, but at least my CEL finally came on. Took it back to O'Reilly's and they read a MAF sensor code and a catalytic system code (didn't ask for the codes, and now realize that was a mistake).
So today I took it to a muffler shop to have the catalytic system diagnosed. They looked at it for 10 minutes and told me they didn't think it was the converter. They said it seemed more like the EGR valve or solenoid, or the IAC. He scanned the codes again and got multiple "running lean" codes (0171, 0174, etc). The guy said I didn't have a vacuum leak, so I think I can rule that out. Unfortunately, the truck idled fine the whole time so he didn't feel comfortable giving me a definitive answer. He told to to leave the EGR valve hose unplugged for a few days and see if anything changes. I'm thinking about running a bottle of fuel cleaner through it or taking off the IAC and/or EGR and cleaning them myself.
Ford - Explorer :: 1999 - Stalls Low / Rough Idle
99 explorer 4.0 automatic, lately been running weird. Starts up but will stall out unless you let it warm up. And idle drops below 500 rpm. And is really rough feeling. To like 2 or 300 rpm, then will stall but will start right back up. When I changed spark plugs and wires problem stopped for about 2 weeks and now is back. And has no engine code.

What can cause my 99 explorer xlt to have a rough idle on initial start ups?(Its worse in the winter time) And sometime after driving places when i put it in park the truck will cut off. It has the 6 cylinder SOHC if that's useful.
View 1 RepliesFord - Explorer :: 2003 4X4 - Very Rough Idle - Stalling If Let Off The Gas
Bought a used 2003 Explorer 4X4 that runs like crap.... All I know is it has new upper and lower radiator hoses, new battery, new brakes, 2 new tires and new belts... suspension seems great and body is nice too. It obviously needed a new radiator and complete exhaust, so I did those. Now it is running better ( I can actually get the RPMs over 1500) but still running rough and will stall if I let off the gas. It will surge and dip in RPMs. Very suspicious of vacuum leak.
Unplugged the MAFS and it roared upon start but within a minute started the sputtering etc. Currently pulled the IAC and check continuity between pins and it was 10 ohms so that passed but there is no continuity between either pin and the case. So this seems to indicate I need to replace the IAC which I will do tomorrow. I would love to find a diagram that displays the vacuum system so I can make a thorough check of it. Also seems to have an oil leak on drivers side valve cover gasket.

so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:

Ford - Explorer :: Stop If Don't Step On Gas After Starting - Rough Idle
1994 Ford Explorer; When I start it, if I don't step on the gas it will stop. If I give it some gas when I start it, the engine will race and then decelerates about 2000 rpms and keeps doing this, it does get better as the engine warms up. But the idle is really rough. It has new wires, plugs, vacume lines, oil change, air filter and battery. If I put the gas pedal to the rug, it will go from 4000rpm back down to 2000rpm and continue doing this as long as I keep the pedal to the metal. I had it put on an analyzer and it didn't read anything.
