Ford Aerostar :: 1986 - No Power / Idle Is Slow And A Bit Rough
1986 3.0 liter. I have a problem, concerning no power. The van starts and idle is slow and a bit rough. Something is not allowing the engine to spool up much past an idle, thus moving past 10 mph is not an option. When you try to rev it, it's like it's either starved of fuel or the ignition advance isn't working. As it is basically winter, with a temperature today of about 25F or less, it was suspected that I'd put in bad fuel (as in, containing water) and possibly the system is partially froze.
When I turn on the key, I can hear the fuel pump pressurize and then shut down, as it normally does. Gas line antifreeze was added but no change; we limped the vehicle at 15 miles or less for almost 2 hours. Likely if the fuel system had ice in it, it would've cleared out by then. As it happened on the road, I'm at the mercy of a shop of which/whom I do not know. Would it be advisable to instruct the mechanic to check for fuel at the "Schneider" or fuel pressure release value, located near the manifold?
Ford Aerostar :: 1995 - Loss Of Power - Stalling - No Codes?
I have a 95 aerostar with the 4.0. After driving a while it wants to lose power. It only happens after the van has been running for a while, at least 2 hours or more. So of course I have mostly noticed it at higher speeds because I was on the interstate going a long distance when it happened most recently. But it has also happened at lower speeds, after the van had been running/driving for about 4 hours. The van doesn't die right off. It is idling as the van slows down. So I can come to a stop, and the van is still running. I can get out and look at it sometimes, it eventually will cut off. Pushing the gas does nothing, other than perhaps encourage it to stall sooner. It is a complete loss of power but the engine remains running at an idle. If I wait 15 minutes it will go a couple more miles down the road. If I wait about an hour, I can get even further. Let it sit overnight and it seems like it will drive endlessly but not so.
If I try to restart it immediately, sometimes it will run/stutter for a moment. I can wait a few minutes and it will run for a minute then die. After repeated tries to get it to start and stay running it just won't, and then I just wait patiently for an extended amount of time (30 minutes or more). Also on a couple of occasions the exhaust has smelled very rich, and sometimes was black. All of this has been in the last couple of days and 600 miles. It isn't throwing any codes.
Ford Aerostar :: 1995 - Loss Of Power - Cylinder Was Dead
3.0 ENGINE - For a year now I could not figure out what was wrong with my van. It has a loss of power low end but seems to run OK at higher speeds. I changed the plugs, wires, cap etc, fuel filter and no difference. I finally broke down and took it to Firestoneto diagnose it. The guy told me #5 plug was foul and had oil on in, said it is possibly the rings. They did not charge me but they also did not do a thorough check either. They did not check the compression in the cylinder or other spark plugs.
Spoke to a guy at the auto part store and asked what I could do. He said change the oil and add a can of restore. Also said to put a anti foul adapter in first and then the new plug, the adapter would keep the oil from fouling the new plug.
I got the oil change and added the restor. Drove it for a while and took the plug out myself, its the 2nd one in on the drivers side. The plug was nasty looking. Put the new plug in and started it up. I can see that there is spark going to the new plug but putting the wire on and off made no difference in how the engine ran, like the cylinder was dead. I took the plug out of the adapter and put it back in, still nothing, I took the plug back out and there was no oil or smell of gas. Fuel injector not working? You would think there would be some combustion with the new plug.
A year ago the problem started where the van would run great one day then crappy the next. Sometimes it would run a few days great(like new) then a few days crappy. After a month or so it just ran crappy and basically has ran the same for a year now. I notice the A/C puts a load on the engine and the A/C clutch will click on and off every few second when the van is in gear but not when the van is in park or neutral. A/C is not low and works fine when driving, very cold. I normally turn the A/C off during take off because it takes off much slower with the A/C running.
The van shows some white smoke when I rev it up real good when I first start it but it does not show any smoke when idle and while driving.
Ford Aerostar :: 1986 - Noisy Rear End - Interchange
I have an '86 Aerostar with a noisy rear end. I've had it checked by both my mechanic, and a transmission shop, and they both say it's the differential, not the wheel bearings. The quote to rebuild is expensive, so I'm looking for a replacement. My question is: What years will interchange with my 2.3, 5-speed '86 Aerostar?

I have an '86 Aerostar with the 2.3 four and 5-speed stick. The shifter is sloppy, and it's often hard to find 4th when downshifting from 5th, and sometimes, it shifts hard through all the gears. Other times, it works fine. The manual says that this shifter was used from 86 to 89 only. Did they use the same one on Rangers? Can I buy a rebuild kit? Or, is this a sign of some other problem such as the clutch slave cylinder?

Dad has a 01 one ton with the 7.3 and isn't real tech savvy so I'm posting for him. He is the original owner and has been complaining recently about the lack of power. Particularly the upper end. He is having to downshift way more often and where he used to not have to. And we've both noticed a very noticeable shake at idle. Not a vibration but a true shake. He changes the oil every 5000 on the dot and I've gone and changed the air and fuel filter and ran hose and see foam and royal purple injector cleaner through it with no results. Truck is all stock with 225000 on it.

I have a 2002 F-250 7.3, 159k on it. I bought it in March, ran AWESOME up till now. I was driving to work last week, check engine light came on, truck lost power and started idling rough. I have a buddy who works for a Ford dealer as a diesel mechanic, he came over with his scanner and laptop. #2,#4,#8 cylinders kept coming up saying possible problems are injectors, harness, rings.. He also did an electrical check, that all checked out. He told me to get injectors, so I got 4 injectors (yes I got the correct #8 injector), valve cover gasket, injector harness and 4 glow plugs.
The parts came last Friday, we did the job and it ran great. Drove it Friday night, Saturday, Sunday morning, no issues. Sunday afternoon we were on our way to a birthday party, truck started doing the exact same thing... Check engine light, rough idle, loss of power. After I got home from the party, my buddy came back over, put it on the scanner again, getting the same codes again. Deleted the codes, ran the tests again, same codes, deleted the codes, rant the tests again, same codes.
He said he is going to come by tomorrow with the box to check each individual cylinder.
Ford 6.7L Power Stroke Diesel :: 2011 - Rough Idle - Surging And Loss Of Power?
I was driving my 2011 the other day home from work and experienced a rough idle. Normally the truck idles pretty smooth. I noticed when I was driving at highway speeds the truck seems to shake a lot. I pulled over and turned the truck off. I did a walk around and could find anything out of the ordinary. I started it back up and no more rough idle. However while i was driving at freeway speeds I could feel a momentary lack of power, then the truck would regain its speed. This would only last a sec or two.
I figured I'd give it a few days.... well now its gotten worse. Its doing the same thing but a noticeable difference in the lack of power. I still have boost pressure and the turbo seems to working fine. Im trying to figure out what it might be. I'll be taking my truck into ford again...

View 5 RepliesFord F-150 (2004-2008) :: 2005 - Rough Idle - Power Loss?
my f150 running right so i can enjoy it like everyone else does. I have a 2005 Ford f150 with a 5.4 auto.
It has a rough idle(shakes the truck), very little power, and poor gas mileage. Randomly It will throw a code for misfire on 1 and/or 3 on start up only. It does seem to perform better within the first few of starting but dies right off after that. In fact i got stuck in the snow the other day and it could barely break the tires loose to try and get it out (almost put in 4low cause i didn't want to hurt the trans). I have replaced:
Cats
Fuel pump
Plugs (motorcraft)
Random Coils
Did the timing chains and phasers
MAF
All new injectors
Intake gasket
Was at my mechanics and had a scanner on it and at idle the 1-4 cylinders are all show a negative cylinder contribution. But when you rev it up they all go to 0 across the board. Was kind of thinking about the Variable Timing solenoid.
Ford - Explorer :: 2007 - Rough Idle / Power Loss Sometimes While Driving
Explorer with 4.0 has a rough idle, just put new plugs & wires, air filter looks good. i did get a new fuel filter as well but haven't gotten to that yet. It has 102k. I have read some info about motor mounts could come lose casing the motor move a little more, not sure about that one. its the wife's haven't driven or looked into it yet, its on the to do list weekend. She also informed that it seems to lose power a little while driving sometimes, thinking possible fuel pump now?
View 4 RepliesFord F-150 (2004-2008) :: 2005 XLT 5.4L - Rough Idle / Loss Of Power And CEL
I have a 2005 F-150XLT with the Triton 5.4L. The other day while driving on side roads (Paved, not back roads) I noticed my CEL on and it was blinking. There was a very rough idle as well as a big loss of power. When I pressed the gas pedal it was sluggish to say the least. I have yet to get a computer on it, since I had to order one. There is also a light gas smell, only smells near the rear of the truck. From what I am guessing, I think it is either a spark plur or a coil over pack, Truck has about 56K on it.
View 1 RepliesFord Super Duty (1999-2016) :: Loss Of Power And Rough Idle
Last night, I left it running while unloading a trailer and come back to notice it was idling abnormal. I jumped in it and tried to move it and there was a noticeable loss of power. I unhooked the trailer and tried to get it home. I only made it 1/2 mile down the road when it started spitting and sputtering (surging ever now and then) to a level that it died completely. I was able to start it back and get it out of the road but had to be pulled into a drive. It got to a point it wouldn't start back at all.
Today it started up however still had a rough idle and really has no power to speak of. The more I messed with it the less power it seem to have.
I have searched the forums and tried these things:
1) Checked the oil and noticed it was on the low end of the operating range. I put some in it to put it back to normal.
2) Disconnected the ICP
3) Changed the crankshaft position sensor
4) I dumped the fuel bowl after it completely died (in case it had any water in the fuel bowl).
The fuel filter was just changed 2 weeks ago. The fuel pump seems to be operating correctly (or it at least refilled the bowl) and started again with a very rough idle.
It doesn't have a engine light on nor do I have anything to read any codes it may be showing.
Ford Super Duty (1999-2016) :: F350 - Power Steering Loss At Idle
I have a 1999 f350 7.3 diesel. If I apply the brakes when I am not moving it is almost impossible to move the steering wheel. I have flushed power steering system. This problem has gotten worse over the corse of owning the truck for the last 10 years. Ball joints and u joints are good. Had to change power steering cooler a few years back, rusted out line, really got gradually from there.
View 9 RepliesFord Super Duty (1999-2016) :: 2005 - Rough Idle / Loss Of Power Under 1k RPM
2005 250 5-speed total oil pressure loss ... At 110k mechanic diagnosed failing phasers from noise, rough idle, loss of power under 1k rpm. (Crew cab long box xl bought new for $25k)(first 100k were from carpenters (hard miles) so this truck is barebones and usefulness is much higher than cash value). Truck has 146k
All symptoms typically disappear over 1k rpm so I have limited idle time and manipulated engine speed to try and maintain 1000-1200 and all has been well for past 36k miles. Today noise (valve clatter?) persisted at all rpm and during a scramble to get off the highway all oil pressure was lost (I'm aware that pressure gauge on dash is not 100% reliable). After total pressure loss I cut engine and called tow truck. Out of curiosity, I actuated ignition and motor cranked maybe two rotations, and then appeared seized. After about 45 min waiting for tow I went back to disengage 4wd and take my rifles and skis out of truck. At this time I actuated ignition again and engine fired and ran as it had for past 36k miles. I drove about one mile constantly watching oil pressure gauge, then noise returned followed by instant drop from normal to 0 pressure (dash gauge) I immediately shut of engine.
I am a mechanical engineer, but not a mechanic. I am familiar with the cam phaser system and I understand that their operation is directly related to oil pressure. Today's temp was under 0'F. I have a very skilled mechanic who works for around 30-40% of cost of licensed shop and I know his skills to be on par.

View 4 RepliesFord Super Duty (1999-2016) :: Hesitation / Idle Rough / Stalling Sometimes - Power Loss
Here is this wonderful 5.4 's issue now, sometimes it will idle rough, sometimes it wont. sometimes it feels like it wants to stall, other times not. if im driving about 30mph up a hill around 1700 rpm, the engine feels like a bucking horse, it will kinda want to produce the power, but cant seem to find it till the trans drops to a lower gear. With this engine power loss is unacceptable because it came out of the factory with no power, i cant afford to loose more.
there is no check engine light. its been doing this on and off for a week. i dont drive it much, may 15 miles a day. i thought maybe it was bad gas , i had it sitting for a month, but since then ran almost 2 tanks of gas through it. Seems to act the worst when driving it, then letting it idle for 5 mins, then drive it again, that's when its very noticeable. no smoke from exhaust, no mixing of oil and anti freeze, plugs are a year old, filter is new.
Ford Super Duty (1999-2016) :: 2002 F350 7.3L - Rough Idle / Knocking / Loss Of Power
Alright, I have a 2002 f350 7.3 4x4 ext cab xlt with 300k miles. Bought in may 2016 with 260k miles and towards November started running rough and felt like a loss of power. Had a no start but a new gray cps fixed that issue. Running fine. About a week later started it up and it had a rough idle, felt like not all cylinders/injectors were working. Was "knocking" and a loss of power. I was in the army at the time and stationed in Georgia, took it to a local diesel shop in Georgia and they confirmed my icp sensor was bad and injector #1 , #5 #7 were bad. Work was busy and money was scarce so I left it as it is and was saving up to buy the new parts. Then one day approx a week after the visit to the shop, I started the truck up and it ran fine. No misfire no knock no rough idle, drove fine for about a month.
In December, I was on vacation in florida to see my parents, drove the truck down, ran fine. While on vacation one day in a Walmart parking lot the truck didn't start up. Couldn't fix any issues then so towed the truck to my parents house. Did more troubleshoot, replaced fuel filter, cps, ipr valve, icp sensor, glow plugs, glow plug relay, ebpv pedestal was replaced with a ebpv delete pedestal. All parts bought oem and/or from riffraff diesel. Still would not start up. So then I bought a refurbished IDM from eBay, oem and then the truck finally started up one day but running rough again like it used to, then it wouldn't start again. So then, I replaced the PCM with a reflashed/refurbished one off eBay and boom truck started up, still running rough but now it starts up every time.
Now, took all eight injectors out and replaced all the o rings. Cleaned them up and put them back in, truck still running rough. Injectors didn't appear damaged nor the wiring harness so now I bought three reman injectors from riffraff. And replaced those three bad injectors. One of them is not spitting oil out the oil spout on the injector.
My dad has worked on freightliner semi trucks for years and is fairly knowledgeable when it comes to diesels. However he did something very amateurish the other day. So two injectors were installed while we were still waiting on the third in the mail. He wanted to see how the engine reacts when that one bad injector was not in play, but instead of unplugging the injector under the valve cover, he cut the wire outside the valve cover to the injector. He stated it's not a big deal and he can solder the wires back together. But once he cut the wire, the truck sounded a lot stronger, still rough idle but definitely stronger. Before, you would be pedal to the floor and the truck barely moves forward but now the truck will lunge forward. A big difference in power.
Now today, third injector came, swapped them out and fired up truck. We didn't solder the wire yet just quick connect, same you would use to connect wires for a car stereo. The new injector was not spitting oil out the oil spout. Even at high rev and truck warmed up. Truck still runs better with that one injector unplugged.
Tomorrow we will troubleshoot if somehow there's wires that grounding out or burnt out somewhere but as of right now everything seems to be in order, the uvch are tight, and no signs of anything burnt.
Triple checked everything, still getting fuel pressure, still getting oil pressure what gives? I also replaced the MAP sensor. Fuel pump is fine, fuel gets to fuel bowl. The next thing I'm thinking is maybe the hpop but we have oil pressure so idk..
