Chevrolet - Caprice :: Buck And Sputter As If Gas Is Being Chocked Off When Going Uphill
I have a 1975 Chevy Caprice Convertible with a 454 cubic inch "big block" engine with a 4 barrel carb. The car is in mint, original condition with 24,000 miles. Usually the car runs flawlessly, however, lately I have noticed that the car doesn't like going uphill. On level ground and downhill, everything is fine. However, when the engine and car are hot, and I come upon a hill, the car will start to buck and sputter as if the gas is being chocked off. A few extreme times, the car has stalled out completely. Once I role back down the hill onto level ground, the car starts up and everything is back to normal. The problem is not noticeable when the car is cold.

1999 Ranger 4.0. I have an issue with my ranger. Sometimes the truck runs awesome.While driving along the truck will miss and sputter and buck, when this happens, I almost can't maintain my speed. Sometimes when this happens if I put the truck in neutral and shut it off and restart it. The problem will temporarily go away. Occasionally it will go away on its own. When it goes away on its own it's like someone flipped a switch and all power is returned and running smooth. When the truck is at idle it depends on the mood of the truck, sometimes it's fine and other times it wants to die. I got to make this truck last awhile longer.

Stopped in the dealer to look at a new Prius. Already have a 05 so I sold on the vehicle but was told some things have changed so I should drive it. I hit the power button and the engine proceeded to make a terrible noise like metal hitting plastic. So I shut it down we popped the hood and restarted, the engine was bucking side to side and finally quit down to a normal.
Granted it was cold (22 degrees) and I don't know when the vehicle was last run. They only have 2010 on the lot, I was looking for a II or III and a nice color (tired of silver and don't want white or black) and this was a red III, only one in the lot and the one they wanted to sell me. Not sure I want this one.
Ford - Mountaineer :: 2004 - Buck / Shake And Idle Around 400 RPMs - Misfire On 3 Cylinders
I recently picked up a 2004 Mercury Mountaineer, 4.0 with 113,000 miles. OBD reader says misfire on 3 cylinders.. Installed new plug wires first.. nothing.. going to install plugs next when she is cold. Now, am I really looking at replacing the coil pack to end the misfire codes? She likes to buck and shake and idle around 400 rpms.. I know that is too low..
View 4 RepliesFord 6.0L Power Stroke Diesel :: 2005 Truck Buck / Miss Not Just Under Load
Truck has not been bullet proofed and has aftermarket air intake. Truck has 185km on it (purchased at 160km a year ago). For the Ham Radio guys out there, this is the most electrically noisy vehicle I've owned with S9+ noise while accelerating and S7 going down the highway ...
The faults show up as:edit Can be hard to start cold, takes couple of tries if it's been sitting for a bit (week or more)
No power when cold, that is a lot of pedal results in little power
Misses a lot when cold
Light blue smoke when missing when cold
When fully warmed up which takes 15 minutes of idling regardless the time of year:under load (heavy acceleration while loaded or not, or just in towing, or carrying) it misses a few times a minute, otherwise runs well
It feels like it just doesn't fire a cylinder if it were a gasser, or as if the spark plug weren't connected, but it's not a constant miss, it is intermittent. No load means hardly any misses. Load means lots of misses even running down the road. Should be pulling hard up a hill where it misses lots more.
What I've looked at :
FICM voltage 47.8 standing, 47.6 cranking and running.
FICM is aftermarket and there are no cold solder joints.
Added Archoil 9100 with no change
Wires to FICM are tight and connectors aren't cracked
edit Wires to Injectors are tight and connectors aren't cracked
Exhaust temps range between 500F and 800F during any of these events
Basic ODB reader shows no codes
I'm looking for a couple of things - I'm not much of a mechanic so this has to go to a shop for diagnosis and repairs. Before I run it someplace, what sort of diagnostic tools should that shop be equipped with to find out what's going on? Also, given what you know of the problem, am I likely to damage things if I continue towing activities?

View 2 RepliesFord 6.0L Power Stroke Diesel :: Surges / Buck At Acceleration - Gallop / Miss / Stall At Idle?
I've seen the gods of the diesel engine do some amazing things on these forums, so after a year of pulling my hair out, I've signed up to try this myself.
This time least year,I bought a 2004.5 6.0L F-250 with 196k on it to haul around the state for my new business. At this time, I knew nothing about diesel engines AT ALL WHATSOEVER, but I've never been afraid to tackle anything and mechanics are not totally foreign to me. Not to mention, I was hoping everything might just go peach-ily for at least a couple years. (for what it's worth, My dad and his family are mostly shade tree mechanics and I'm a power plant operator so mechanical concepts are not totally foreign to me, just never had a diesel before)
To begin, I purchased the truck and everything was fine for about 2 weeks. Then abruptly one morning I noticed a couple of hefty surges on the way to work. Then, on the way home I thought all was well until about half way home, it did it again! as I was pulling up, it galloped once I pulled my foot off the pedal. like ba-DA-DA-DA-da-da-da-da-da-da-DA-DA-DA-DA-DA-da-da-__ and then STALL! Shaking with concern over potentially an awful purchase, I turned the truck back on only to find... that it's fine?!?? No problems for the next two days and then it happened again. then good for a week, then again. then good for 2 weeks, then again. so then I bought auto enginuity and an edge insight to do some troubleshooting. Let that sink in as I explain it's history a bit.
-All but one injector is ford remanufactured the other is stock (was never told which one)
-replaced head gasket with another OEM
-ARP Head Studs
-EGR delete
-HPOP AND STC fitting both replaced
-FICM replaced
-Oil cooler replaced 50k ago
-ICP and pig tail replaced right before my purchase
- Has been through roughly a handful of ICP's since I've had it (I'll explain)
-I've cleaned the EBP tube a lot and updated it to the newer ford sensor with the flare fitting
-I use Rotella T6 5W40 and CAT ELC-1 Coolant.
-Deltas are under 10 at normal driving
-I typically drive under 2200 rpm until warm then like a banshee at operating temps.
Now one year later, its not fixed, but I feel like I'm close.
The DTC's I have seen are ICP sensor circuit intermittent (I think po2884) and Power Blance contribution failure from cylinders #2 #7 and #8 but never at the same time.
Every time I replace the ICP, it will be problem free for about 6 weeks and then it will return full force (surging and galloping when warm about 50% of the time)
During a possession I see the following:
*Cylinder power contribution test yields no issues at idle or when cold. when "possessed", the whole baseline across all cylinders goes up and all cylinders dip and return at random. none singled out
*ICP voltage fluctuating from ~.6v to 1v (.24 @koeo) *Also during a surge*
*ICP PSI dancing up and down ~600 to 900psi (0.0 @koeo and ~500 at normal warm idle) *Also during a surge*
*IPR% bumps up and down ~25% to 30% (15%@ koeo and 23% at normal warm idle) *Also during a surge*
*FICM Voltage anywhere between 47.5v and 49v
*EBP is normally 15-20 psi
*Boost is 1-7 normal and is not affected by "possession"
These numbers have taken a long time to get since it will only be possessed for about 3-10 seconds at a time and then will disappear for days. The stall has only happened about 5 total times in a year. The surging is much more frequent. I usually get a buck or 2 on any given trip that is longer than a half hour but NOT IMMEDIATELY AFTER AN ICP REPLACEMENT.
On one occasion, I noticed that the ICP PSI actually tanked to about 350 right before the IPR went from 25% to 40% right before a posession. I was driving about 35mph through town at the time.
Here's my thoughts...
- Did that one occasion clue me in to an intermittent HPO system leak causing the truck to briefly over-compensate by spiking the IPR?
- Is my ICP pig tail jobby done incorrectly? If there was a short, wouldn't I see the volts drop to 0? I have another one and will replace to rule it out.
- I have yet to test my fuel pressure, but I figured if it was low, I would have lost injectors by now. (I replace filters probably too often but next empty tank, I'm dropping it and checking the screen and strainers)
I should also mention that I have buzz tested the injectors and I can hear each one clear as day, and that for REALLY long trips, it actually returns to normal. In other words, my window of death is between 30min and 2hrs of driving; invincible after.
Sonata NF (2006-10) :: Rough Idle / Sputter And Lurch In Gear Only
2006 Sonata V6 with 98K miles. The car has developed a rough idle, sputter/lurch while in gear, but not park or neutral. No CEL/codes. Have already replaced the spark plugs (OE), throttle body/FI cleaned, MAF cleaned, new air filter, coil packs OK... Mechanic said no vac leaks, FI spray pattern good, good fuel pressure, etc. Vibration dampener looks ok, no separation or wobble. Another post mentioned a power steering pressure sensor, which I will have checked, but the mechanic is at a loss.

As listed above I own a 98 Volkswagen Passat. It seems to run just fine for the most part, but if I push on the gas and let off I notice a slight sputter. The RPM's will drop to about 800RPM up to 1000RPM and back down again and it will eventually stabilize and idle fine. My only guess that I have so far that I read on a post somewhere is that the EGR Valve tends to get gunked up and stick. I will try to clean that off.
View 12 RepliesPrius (Gen 2) :: 2008 Car Decelerating With Idle / Sputter After Robotic Tunnel Car Wash
I took my 2008 Prius through a very aggressive robotic tunnel car wash and as soon as I left the car and drove off I noticed that the car was idling very rough. It has been continuing to do so for the past three days. Every time I drive the car, even if I'm not accelerating and the car is just decelerating, the car seems to have a very rough idle/Shake/sputter to it. It idles rough, it decelerates rough when foot off the gas pedal , and it's making a lot more noise than usual.
It used to decelerate quietly before the car wash. And this car wash was wack, like hyper pressurized. I mean when it was spraying down the windows it felt like the windshield was being shot. I just bought this car a few months ago.
Ford - Focus :: Sputter And Die When Running On Idle For A Few Minutes / Cannot Turn Left
I drive a 2007 Ford Focus and when the fuel level gets to half a tank the car tries to die, and quite often does, when making a left turn. About 1% of the time it will do it when making a right hand turn. It will also sputter and die when running it on idle for a few min. It first started doign this at 1/4 tank but has gotten to where it will do it at 1/2 now.

I have a 2000 3.0l ranger. I have been battling an ignition problem. every time the engine is cold it runs terrible like only 3 or 4 cylinders running terrible. if u put a timing light on the wires the pulse comes and goes on random wires. and when it quits that it has a random sputter at idle and misses around 4k when u get into the throttle ...
I have replaced plugs twice and the coil with motorcraft parts and the wires are new autolites. I have also replaced the thermostat and fan clutch it was getting hot in the middle of this other issue ...
Every time I replace something it runs great for a few days then back to running terrible again. am I missing something else do I need to look at a computer or map or tps sensors, or something like that ...
Ford F-150 - 1997-2003 :: 2002 - A/C Causes Rough Idle And Stall / Sputter And Die On Restart
I have a 2002 4.6L FX4. When I run the A/C for an extended period (say 15-20+ minutes), it will start to cough and sputter and eventually just die. It will restart but run rough and cough, sputter, die.
If I turn off A/C and let it set a while, it runs fine. No check engine light. Possible EGR problem????
Ford F-150 (2004-2008) :: CEL On - Misfiring Enough To Feel Consistent Buck From The Engine
I am having my trouble with my 06 F150 with the 5.4 V8. I purchased the truck back in the spring and shortly after the truck started misfiring. It was throwing P0306 for cylinder 6 misfire and that was the only code thrown. Seeing as it was out of warranty and right at the 100k mark I replaced all the plugs with Motorcraft plugs, and the plugs that came out were Champion, so it had already been done at least once. This didnt solve my problem at all so I started digging deeper. I replaced the coil pack on the number six cylinder thinking it may have gone bad, but this did not fix my problem either. I had somehow overlooked that the number two cylinder had a Masterpro coil pack that was made in Taiwan or somewhere like that, and after using the Motorcraft coilpack I had pulled from number 6 on cylinder two all my problems went away...until recently.
At the beginning of August my truck started the infamous ticking sound that we all know about. I ignored it for a while, but as I was moving off to college the misifre returned while going down the interstate at around 65-70mph. The truck lost pretty much all power and I coasted off the next exit to see what was going on. After making it off the truck was running perfectly, so I poked on home on back roads at slower speeds to be safe. The next day I took it to the Ford dealership to have them run a full diagnostic scan to determine anything that could possibly be wrong. After sitting in the waiting room for three hours as they searched the guy comes in to let me know they have ran every test they could and nothing was showing up, but the lash adjusters (lifters) on the passenger side of the engine needed replaced as that was what was causing the ticking sound.
Well today I start my truck to come to school and it felt slightly different, but once I accelerated all was fine. Once i left school this was another story though. The CEL was on and the truck was misfiring enough to feel a consistant buck from the engine. I pulled the codes and it is now giving me P0307 and P0316 which are misfire in cylinder 7 and misfire upon startup. What could this be knowing all the plugs have recently been changed and the dealer just inspected the entire engine?
Touareg :: Starts To Idle Erratically - VW Engine

2005 Echo auto 120,000 km
I have intermittent misfiring (a few seconds every couple minutes) and get the codes 301 and sometimes 304/300. I cant drive out of my driveway without a sputter and when I turn into a parking spot or make a quick stop the problem is magnified. I initially suspected a wiring / coil issue but here are my results:
Shuffled coil packs. (1/2 & 3/4)
Shuffled fuel injectors.
Good compression.
Swapped ECM.
Inspected wiring harness.
Goof EFI / cutoff relays.
None of these led to any change in the codes (300, 301, 304)
Yesterday I swapped the fuel pump and it worked flawlessly for an hour of city driving (first time in two months) ... then the issue returned as before.
Ford F-150 (2004-2008) :: 2005 - Truck Starts To Sputter And Kick A Bit When Driving At Low Acceleration
I have a new to me 2005 F150 with 86,000 miles. When I am driving through town at a low acceleration or a constant speed at between 40 - 50 mph the truck starts to sputter and kick a bit. When I give it some gas the problem goes away. This gets worse when I pull my bass boat, and starts at around 30 mph. When I hook it up to a reader I get a P0316 code. Only code I get.
Also when I am driving through my neighborhood between 20 - 30 mph I get a noise that sounds like there is a plastic bag stuck under the truck. I have checked under the truck to see if the firewall is loose anywhere, but could not find anything. Other than those two issues the truck runs great. What these problems could be?
