Engine is sputtering when accelerating?

Hi:

Before considering a fuel problem, what size V8 is it and is the check engine light on? It sounds like the engine is misfiring?

Has anyone "washed" your engine?
If it just shakes alot it's (probably) a COP (coil-on-plug) or spark plug failing.
If it FALLS FLAT -check fuel pressure - it's very easy - there's a shrader valve (like a tire valve) on the top of engine - just slip a guage under the wiper and go, being careful not to turn on the wiper if it's raining.
To check COP's (and other ignition/fuel checks) you'll need to have a scan tool that shows at least a code for what cylinder to check, or better yet that shows crank speed and tells which cylinder(s) not contributing in real time.
These are both common problems and is where I would start. (There are many more [less common] things that happen)
If you pull a COP out and the boot has a big crack - replace ALL the boots. (COP's are OK)
If pressure IS going away don't just replace the filter, replace the pump at this mileage if not been done before...

My 2000, 2WD, EB, 4.6L Expedition 139,000 miles sputters idle, in gear and while driving. Fuel system cleaner has no affect. Appears i would have to disconnect the fuel injection to change spark plugs. i posted my own question as well. Can someone confirm the need to disconnect Fuel injection to change plugs?

Hi:
You should be able to work them out without removing the fuel rails. I have the 5.4 and thought the same thing, but was able to do it.

Driving down the road and the the engine started making a loud sputtering noise it sounds kind of like air pushing out of something, And seemed like the engine was going to die. There has been a tick sound coming out of the engine for a couple weeks that a mechanic said was just the valve lifter or something like that. Is it related? Or something else? What could be the problem here??

Based on the description of the symptoms, there has been a lot of trouble with Ford V-8 truck engines popping out a spark plug, usually the rear one on the passenger side. There is supposed to be a repair kit for that but due to access problems, I think the cylinder head has to be removed to do that repair. The original ticking would have been the exhaust gases sneaking past the loose spark plug.

Thank you thank you oh so very much, you nailed it right on the head. That's exactly what was wrong now it's purring like a kitten!!!

All right! One in a row. Happy to hear it's solved.

What cause my suv to shake when I give it gas my rpms idle between 600to 800rpms in drive at a light ans sputters on take off?

It could be a few things. First, has the check engine light come on?

Let me know.

hello i have a 2000 for expedition. I had no choice but to drive through some water on the road during a heavy downpour two days ago. one was rather deep. today a check engine light came on, flashed a few times and turned off. over the next twenty or so miles home the expedition sputtered (i'm guessing is the best wording for it) Any ideas as to waht this could be? I'm sure it has something to do with driving through that water two days ago.
thanks

take to any parts store and they can ck. the codes for u and then u will know.

Engine Sputtering while in idle and in gear. Service Engine Soon indicater is on. Fuel systen cleaner has no positive affect. Appears will have to remove fuel injector lines to replace plugs? Can you provide some insite as to how i should proceed?

Get the code(s) from the Check Engine Light. If you don't have a scanner, you can try the larger franchise auto parts stores such as AutoZone or Pep Boys or Advance Auto Parts. They can scan your car for free. Don't fall into paying for gettiing a scanner hooked up. Shop around. There's plenty of places that'll do it for free.

Write down the code(s). The codes are very specific, so be sure to write each one down. Post the codes on the forum....then you can proceed.

The code(s) may not be the absolute answer to your problem, but it'll point you in the right direction.

I started my truck this morning and went to hit the acceleration and the truck sputters alittle. I replaced the spark plugs a year ago, but not the wires/ coil packs. Can someone help me with answer's, because I really don't want to pay a mechanic if it is a diy project.

The only thing you can do to start is to have the diagnostic fault codes read and recorded. The people at most auto parts stores will do that for you for free. That's where the mechanic would start.

Get the codes read first. Is there no other informative information relating to the matter?

No. You haven't provided any useful information or test results to analyze. "Acceleration" can mean going from standing still to 15 mph or from 65 to 80 mph. To some people, "sputtering a little" means the vehicle barely runs without three passengers pushing it. Some people get excited over the tiniest thing we don't even notice.

The repair might very well be a do-it-yourselfer project, but first you have to know what's wrong. I can't tell that over a computer. I know a few people who are dangerous if they get close to a screwdriver. Other people make beginning mechanics look bad. I need to have an idea of what you can handle when working on vehicles with way too much unnecessary technology. I've had people get angry with me and call me every name in the book after I told them what needed to be done, then they attempted it themselves and damaged something expensive. I don't have a problem steering you in the right direction, but exactly what kind of answer are you expecting? You have an engine running problem and you didn't even bother to list which engine you have.

You can't call your doctor on the phone and say, "I'm in pain", and expect a diagnosis. You might have a hang nail, cut your foot off with a chainsaw, or you ex-girlfriend came back! At the very least, he's going to ask you a few questions to get started. Reading diagnostic fault codes is always the place to get started. Unfortunately, only Chrysler makes that a 30-second do-it-yourself project. For all other brands, you either need a code reader, a scanner, or there's some terminals to connect in the diagnostic plug. Connecting terminals went away with the new emissions systems on all '96 and newer vehicles, so unless you want to invest in a code reader, you need to go to an auto parts store.

You can find decent code readers on eBay for less than a hundred dollars. One diagnosis from that code reader will cost less than an hour of diagnostic time at a shop.

Point taken buddy. Didn't mean to offend if I did. I will stop at auto zone and see what they get from the code reader. Until I find out..Thanks!

Not offended. I just love using my "I'm in pain, . . . why" line but I don't get the chance very often.

A few weeks back it started having difficulty starting occasionally. Sometimes It would crank but not turn over unless I gave out a little gas. It was not often enough that i felt it needed to be fixed yet. My son told me he thought it was the crank shaft sensor. Well two nights ago, driving home in a snow storm it started shuddering with acceleration any acceleration five mph or sixty mph. When you take your foot of the gas it stops. The idle is very low now and also vibrates in park. Could this be more symptoms of a bad crank shaft sensor or separate problems. Now, a few months back she shot a spark plug out of her head. Common problem I am told with the engine sizes for this year. We took the head to machine shop and had an insert put in. I think it might be a bad coil that got damaged when the spark plug shot out. Any help is very much appreciated.
Update**
Changed the crankshaft sensor and no change.

Sounds more like an ignition problem. i would be making sure all plug and coils are okay, and do a compression teat as well. just to be sure that there is no underlining problem.

I have a 98 expedition, 5.4l. I'm having an issues with a light hesitation upon taking off from a stop or speeding up. If I'm on the highway and try to lightly speed up it kind of hesitates. It shifts fine and runs fine otherwise. The check engine light flashes at random at highway speeds but never when I have it sitting at AutoZone. I guess it's not storing the codes cause it always passes a scan. I'm thinking it could be one of the o2 sensors maybe? I just don't feel like paying the Ford dealer $100 to do a diagnostic if I don't have to! Help!

If it stutters and hesitates you may have a cylinder misfire that is causing it.Those engines have coil, injector issues that cause misfires.Has it been tuned up with OE parts? If not start there. A scan tool will most likely be able to read the"freeze frame/failure records" or cylinder misfire history to find out which cylinder it is.

The vehicle ran fine up until yesterday. We've had it a total of 6 days and.now.it.seems tp have a vibration or shudder within the 40-55 mph range. It only does.it.when you accelerate between 40-55 mph. As soon as you let off the gas.it stops immeadiatly. Also got it within vibrate/shudder range and put it in neutral a.d.it stops then as well. The check engine light doesnt work i guess due to blowed bulb but i took to local autozone and its showing.up that it has a misfire on #3. Mind you the vibration / shudder is quite noticable.as it sort of feels like you are rining over the bumps.they put in the road to slow you down. Checked the wheel bearings and they have no play movement. Checked the ujoints, they seem fine as well. We traded for.this vehicle.due to having another child amd dont have the money to take it to a shop. My questio is can the misfire on #3 be causing this bad of a vibration/ shudder? Or could it be low of differential oil? As i have heard it being low of oil may cause a shudder. Havent checked differential oil bc bolt is stripped and will have to possibly weld extention to it so i can remove it. The trans seems.to change out just fine, it picks up perfectly, runs smooth except a little at take off(around 5-10mph) and around the 40-55 mph. Cranks fine and everthing else. Have also noticed a little rough idle in drive while stopped but nothing real major. And have also turned overdrive off and still does the vibratio/ shudder at same speed levels. Thanks!!! Any help is much appreciated. As we cant afford to replace anything major which is why we traded for the expedition anyways. We figured it was a decent car and more room. It was a decent car for about 5 days, after that we dont know.whats going on

Yes, Change the #3 coil and plug, a misfire can cause the problem you are describing.

Let us know what you find

Best, Ken

i have a 1997 ford expedition that i bought about a month ago. today while driving it it's starts sputtering and kinda feels like it misfires. a friend hooked a device to it and said something about the 02 censor and heater core. what doeas that mean? it is easy to fix? what can i do to fix it?

The O2 sensor may be coming on if there is a misfire. As far as the heater core, there are no codes for it, so I don't know what he is talking about.

Now, has he scanned the compter? Was the check engine light on?

Let me know.
