Accent MC (2006-11) :: Suddenly Started Running Real Jerky, Rough / Misfiring

Our Accent has just about 86k on it now, back in November it suddenly started running real jerky/rough, misfiring kinda thing. So I was able to drive it to my local repair shop and they found a bad coil pack on #3, so they replaced that and put in new plugs while they were doing it.

Just Saturday we were shopping about 20 miles from home and cranked it up to go home and started doing it again, pretty much identical symptoms, runs out normal at certain RPMs so I knew it was probably same thing...I was able to get it home and then took it in this morning and sure enough now #1 is shot. So they are replacing that. They want about 30$ more per coil then I can order them for myself online so I didn't want to scarf up the money for the other 2 that are still original.

Ignition - Kia - Rio - Sparkplugs :: Check Engine Light Came On And Car Started Running Real Rough

I have a 2008 Kia Rio, 4 Cyl 1.6L, and recently the check engine light came on and the car started running real rough after getting the timing belt replaced at firestone. I took it back to Firestone and they said that 2 of the cylinders where misfiring and i need to replace the ignition coils and the corresponding spark plugs, but that i also want to get a catalytic converter cleaning or flush or something like that because of the unburnt gas that was running into the converter. Is this true? They want to charge me another 100.00 for the cleaning on top of the 300.00 to replace the 2 ignition coils and spark plugs, should i get this done or can i clean it out myself?

Golf/GTI VI :: CEL Came On And Then Car Started To Run Real Rough

The Basics: I have a 2011 GTI with 44k on it. First GTI, I have had it for a few months...

I was leaving for work yesterday and the CEL came on and then it started to run real rough. I pulled the codes with a auto zone scanner and I got these:

P2015 - sensor 1 bank CKT range/perf

P2279- air intake leak

P0300 - multiple misfires

P0301-P0304 cylinder 1-4 misfire

I did a bit of research on here and it sounded like a PCV valve. So I picked one up and I installed it. Problem did not go away. I then read that maybe pulling the battery may clear the codes... It did not. Now I have a lot more lights on.

Prius (2004-09) :: ICE Running Rough For A Couple Of Seconds When First Started Up

Am I correct in thinking that Toyota recommend changing the spark plugs at 100,000 miles on the gen II?

The reason I ask is because on a couple of occasions the ICE ran rough for a couple of seconds when it first started up like it didn't have a spark or something on one of the plugs. Also I've noticed an slight drop in mpg, not just due to the time of year either. In winter I normally average 48-50mpg (UK) but I'm struggling to get mid 40's ATM. My pri has covered 75,000 miles so was thinking of changing them now to see if it improves?

Ford Excursion :: Running Really Bad / Misfiring / Smoking And Sounding Real Rough

So Friday before last my ex laid down on me while i was headed to work. So I parked it in a walmart parking lot and caught a ride to work with a friend then had it towed home that evening. Problem i was having is it started running really bad, miss firing, smoking, and sounding real rough, but I wasn't getting any trouble codes. So after both uvch's, icp, ipr, icp pigtail, checking fuel for water contamination and pulling my hair out, i decided to check the oil and found it to be 4 quarts low. Talk about feel like a knuckle head.... While it was down it did receive a new water pump, a diesel site 203* thermostat, new billet thermostat housing, Gooch's Radiator Flush Procedure, and some fresh rotella etc.

Golf IV / Jetta IV :: 1999 - When Pulled Out Of Driveway Car Started Running Rough

I have a Jetta Mk IV, yesterday I went to go drive it and just as I pulled out of the driveway it started running rough, so I pulled back in the driveway and the coolant temperature sensor light came on, then the check engine light. and then it died. Then today I tried starting it, and it will only start and run if I have the gas pedal all the way to the floor, and it runs really rough. Then it will die. I thought maybe the coolant temp sensor since the light came on. I replaced that, and it still does it. I'm leaning towards a head gasket.

Ford 6.0L Power Stroke Diesel :: 2007 - Real Rough And Stalled - Fuel Pump?

I have a 2007 F550 with a 6.0. Truck started running real rough and stalled. I was able to start it back up after a bit but within a few blocks it did the same thing. Was very similar to problems I had with clogged fuel fuel filters before I changed the tank to a plastic one. I pulled the filter and housing on the rail and cleaned and replaced the filter. There was no debris in there. Changed the filter on top of the engine too. Cycled the key 5-6 times. I could hear the pump running but the filter housing on top of the engine did not fill up; all I saw was a very little bubbling and gurgling sound.

I opened the drain on the rail filter housing and a little fuel came out but not as much as it should have. Cap is tight, don't see where I could be sucking air. I'm thinking the pump may be shot? Only other thought I had was maybe I switched the plugs on the housing on the rail but I really don't think I did. There are 2 plugs on the right hand side. Black plug is plugged into the lower position parallel to the ground while the gray plug is in the higher position.

Golf IV / Jetta IV :: VW 1.6 SR (AKL Engine) Rough Running / High Fuel Consumption

Regarding my problem (outline below):

>> Went for a refueling stop, and thereafter proceeded onto the highway

>> Approx. 500m into the drive onto the highway the car started jerking and running rough with an initial puff of smoke (none thereafter)

>> Immediately after this initial jerking/shuddering there was a significant increase in fuel consumption i.e. from a familiar 8.2L/100km to 18L/100km in the cruise

>> We continued driving not knowing what it was (I suspected a spark plug may have stopped working)

>> Pulled up at the gas station to observe what went wrong inside the engine bay - no signs of any leaks, fuel sprays, etc. but only that the engine was shaking

>> I checked the rear of the car while the car was idling and observed a pulsating sound...some light smoke and a fuel-rich egg-like smell

>> Asked around and I was led to think the catalytic converter was ruined, so the next day I had the catalytic converter cut out

>> After removing the catalytic converter the problem persisted...although the engine operated with slightly less flow resistance

Attempt at diagnosing the problem

>> My wife called in a technician from BMW at Canal Walk to come have a look and what errors were flagged

>> The tech ran the diagnostic and no fault codes were indicated, except a few short circuit faults due to my incorrectly placing -ve on +ve when I tried to charge my cars battery with jumper cables

>> He proceeded to ask if we changed the spark plugs, I said yes. He then looked at the oil on the intake manifold and said there could be a torn valve on the intake manifold and that air that is not measured by the air mass flow sensor is entering the engine, which is causing the car to rev hunt (this problem of rev hunting has been with us for a while). The engine also shuts down uncommanded at stops and sometimes between shifting gears with the subsequent loss of power steering (very dangerous!!)

>> We also had the O2 sensor replaced a month before this occurence

The images attached (#1- #3) are marked up to indicate the component I am referring to.

Went to Cape City VW in Cape Town and the part number for that orange thing/diaphragm is 06A 198 205A 'Repair kit for valve'. Is this significant? The car sounds as strange at idle...as if has noisy valves. I can upload (if there is an option) a sound clip of how the car sounds if this assists.

Ford Super Duty (1999-2016) :: 2006 5.4l Runs Rough For About 10 Seconds When Started

Have a 2006 F350 5.4l that is mainly used as a plow truck. I drive it at least once a week when not plowing just to make sure it runs ok, etc. Only put on about 2,500 miles per year. Keep it in good repair - not by me, but by the dealer or mechanics.

Problem - last two times I started it, it started ok but runs real rough for about ten seconds. Sounds like the engine is going to die. After about ten seconds, it "catches" and runs normal. Have no problems when driving it. If I restart it, it doesn't do this, so it seems to only happen when the engine is cold.

Battery was brand new back in Sept. All plugs were replaced maybe 3 years ago, as was the cat converter and muffler. Run non-ethanol fuel. What might be causing it before I bring it in.

Golf IV / Jetta IV :: Turned Over / Ran For About 2 Seconds And Shut Down

So I go to start up the old girl the other day and she turned right over, ran for about 2 seconds, and shut down. I tried to start it again with the same result. When I turn the ignition forward, before starting it, this image with a car and a key below it starts flashing on the gauge and the odometer starts flashing "service". I tried using a different key with the same results, what this might be?

Touareg :: CEL Turned On - Engine Started Running Rough

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.

Ford - F250 :: 1984 - Started Running Little Rough?

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.

Ford - Explorer :: 1993 - Intermittently Started Running Very Rough

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.

Ok just bought this truck ran fine. Put a sct tuner on that the truck came with and some how got the egr turned on. It had a egr delete so it was smoking and finally found it out that it had turned on but fixed it. Now we have another problem, it will start up and run fine and about 45 seconds it will start running rough and go into a limp mode. It will run rough and starts to die slowly and when it starts to die there is no throttle at all.
