Ford - F250 :: 1984 - Started Running Little Rough?
Apr 1, 2016
Just replaced my rear gas tank. Drove for a week with no big issues. Started running a little rough just thought it was debri in the fuel line. While it was sitting for a few days fuel was coming out of the carburator. It drained 15 gallons of fuel from the tank. There was pressure building in the tank when I took off the gas cap. Dropped fuel tank and everything seems to be hooked up ok. Put it back now added gas now the truck wont start even using starting fluid.

I have been puzzled to why my truck isn't running right. We were driving down the highway one day and*then all of the sudden it starts running really rough. I changed MAF sensor, plugs and plug wires, oil change, fuel filter and air filter. Still doing the same thing. What this could be? 2003 ford sport trac..

I have a 93 Ford Explorer, manual transmission. About a month ago it intermittently started running very rough. I does this wether the weather is rainy or not. The engine has done this when it just started up, cold, and when it's been fully warmed up. I have been able to drive it, but it has been quite a challenge. When running, there is a very noticeable noxious exhaust smell. The check engine light has come on some of the time. When the eec codes were checked it only revealed 522, the car wasn't in park or neutral when running the test.
I have tried clearing and rerunning this test several times, yet 522 still shows up. No other fault codes. Don't know how this would cause engine to perform so bad. The fuel tank has been near full when it happened so I believe the gas to be good/ no water. The engine has a lot of mileage on it, over 200K, so I'm not sure if something inside could be malfunctioning, but don't know how to check. The car will run for days very smoothly before this happens again. I have changed plugs, wires and the pcv valve and it still occurs. It's like the engine is hitting on one cylinder when it happens.

I have a Ford F150 XLT. I have 67000 miles on it and the other night it just started running rough out of no where near idle. Once you got over 20mph the rough running would go away. I took it to get an engine change and engine flushed but it came back. It doesnt always run rough near idle or below 20mph. The Ford dealer says my engine has only 22 psi oil pressure near hot idle and cant engage the VCT phazers and they want to replace the whole engine.

My wife's car suddenly started running rough. 2005 Taurus, 6 cyl, 3L, OHV, 83K miles. CEL came on and code came back as "P305 - cylinder 5 misfire detected". As a side comment, her tachometer has been fluctuating big of late as well.

I have a 2001 F150 4.6L auto. This truck suddenly started running rough. Cleared all codes and re-scanned after starting truck. The codes are as follows; P0135, P0155, P0443, P0740, P0743, P0758, P1451, P1460, P1747, and P1760.
My question is; is it normal to have this many DTCs come up at once? Could my PCM be faulty causing this problem? Can you swap a pcm from the same year truck with the same options without reprogramming?

Ok on the way the my 1997 f150 4.6 L 180,000 check engine light started flashing and running rough and then the light went off, Also we took the Aftermarket Dynomax muffler off of it earlier today if that makes any difference, it still has the Cat Converter, New Plugs and Napa Wires.....

So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.
Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.

Since our weather has returned to the cold side......my truck has started bucking and hesitating at 45 mph with EOT @ 130 and ECT @ 140. I can gas on it and it will clear up/let off and it would start up again once it gets below 50 mph. Once the deltas reach 150+ it clears up completely. Its never done this until this week. FICM volts are steady @ 48V. What is causing this or what to look for?

2003 ford explorer 4.6L. This truck will start and run rough high temp low oil light come on and temp gauge is pegged hot. Oil gauge is fine though, checked oil its fine.
I checked coolant reservoir its ok.
If I shut truck off and restart it will run ok and rev like normal and then all of a sudden go into limp mode and will misfire etc...
What sensor seems to be the main culprit?cht sensor???

Our '99 Ford F250 V8, 250,000 miles was running very rough, they changed the plugs and 1 coil pack, 70 miles later it was running rough again, they changed another coil pack, 70 miles later it was running rough again, another coil pack. It is running well now, but it's only 15 miles. will this keep happening until all 8 coils are replaced, or is something else causing them to go bad?

I have a 7.3 that's running rough. Started it the other day it ran alright but started blowing white smoke. Bought a oil and fuel additive i was going to run through it. Came a few days later, it stated up and was real loud and sounding like it was loping. It blew a good amount of white smoke, but it just smelt like real heavy diesel. Now i can only turn it over and it won't start.

I just rebuilt the carb on the truck, it has the 2.8L, and when I went go go start it, it cranked for awhile until fuel filled the bowl, then it started and revved up high, I shut it off immediately and it turns out the throttle linkage was binding for some reason, I fixed that but now it wont restart.
I was cranking it for a while and gas started spewing out of the top, so I took the top of the carb off and reset the float height and now it doesn't spew gas.
I pulled the plugs and checked for spark and it's a really bright blue spark. I'm thinking it's just flooded, lots of gas on the plugs? I'm just waiting for it to clear out now and trying to brain storm what could be wrong.

Well it finally happened, a couple of weeks ago I was headed to an MX race and my check engine light came on and it started running rough. Long story short a piece of an exhaust valve broke off and went out through the head. Dealer has been great even though I was 300 miles from home and they did get me a rental(small POS SUV). Truck was supposed to be finished this week, but now they are saying the head gasket is on back order and they probably won't have one until the middle of April......... I can't be without my truck that long, but not much I can do. By the way truck is completely stock with just under 20K on it, and I have never had any issues with any of my Ford trucks or Ford diesels, even my old 6.0.

2002 Ford Ranger edge 3.0 flex ... Truck was running fine and giving me no issues. I woke for work the other day and went to get coffee and truck wouldnt start. I could hear fuel pump running and knew it wasnt that, it was acting flooded. So today I pulled fuse from fuel pump relay, and got it to start. Put the fuse back in and ran to gas station. On the way to the gas station it started running really rough, very low and rough idle, trying to stall out. I noticed it had black smoke coming from exhaust. I got it home, and got it to start barely, and it has the same very low and rough idle, but my oil gauge was going crazy, flickering back and forth all crazy, and the idol is terribly rough and eventually stalls out. Earlier today I did put new spark plugs in it, but not sure that has anything to do with the issue. I also hooked it up to a computer and it isnt throwing any codes.

I've been clambering over the truck (bought unseen) and working out what needs doing - and have noticed (glaring at me) the lack of belt running from the Fan Pulley up to the AC Compressor... I'm guessing the AC didn't work and this was a 'simple' way to de-commission it?
Is this a common 'fix' or do I need to worry and get belt on there? AC in the UK is only needed 3 days a year (if were lucky) so not worried if i don't have it.

I have a 1999 F250 Ford with a V-10 gas engine. It has 65000 mi. Mostly, it starts and runs great. However, when its 10-15 degrees F, it has a hard time starting. It may start and run very rough - then smooth out. Or it may not start- I come back in 2-3 min and it will start. Once it starts and gets past the rough/missing stage, its fine. If the temp hits 25 degrees F, it usually starts just fine.
There are no warning lights and I've taken it to 2 different car parts place and plugged in a computer- but it shows no alarm code. I've taken it to 2 mechanics and told them they had to work on it first thing - when its 10 degrees.
Once the temp reaches 25, it'll start every time. Both mechanics found no problem starting - I'm sure they didn't get to the truck until it warmed up. Its hard to fix something that works fine. I don't know where to look, but I don't want a truck I cannot trust to start. I've changed air, fuel filter and spark plugs.

I have 2007 explorer with the 4.6 V8....
Recently it started running horrible. Rough idle, drives badly, hesitation, etc. Check engine light is on, code P0171. I cannot find a vacuum leak, and i am pretty much at a loss. Before it started running poorly i replaced the thermostat, and flushed the coolant. I am assuming this is a coincidence.

I have a 2006 E350 van, just recently had passenger side injectors replaced along with dummy plugs and stand pipes. I was at the car was spraying it off and noticed it started running rough, just figured maybe some water made its way into the engine bay and something got wet as it was running great. Well its stayed that way and i am getting codes p0264 and p0276. Digging around on the net seems like its ficm or wiring, ficm is 48 volts and 13.5 volts, connectors are on tight and i dont see any wire chaffing kinda stumped. hoping its not 2 bad injectors at once.

This weekend my CEL went on and stayed there. Everything seemed otherwise fine until yesterday, when the engine started running rough (like it is missing) and the CEL will flash on and off periodically. When I got home, the exhaust smelled like gas. I have an appointment with the dealer one week from today, and am driving my "spare" car in the interim.

I have an 2003 F250 7.3 Diesel 4wd. Yesterday I knew I was low on fuel but I don't think I ran out of diesel. My gauge was above the "E". 50 miles left on my overhead readout, but you never know. All of a sudden the truck misfires and is running very rough before it dies on me. I get it towed home.
Thinking that it possible I ran out of fuel and screwed up my fuel pump, I bought a new fuel pump and fuel filter, installed them and I have the same symptoms. I am guessing I lost my prime, who knows. I have 180,000 miles on it and haven't ever had engine problems.
