Jaguar - Xj6 :: Misfiring Cylinder 5 / Car Started Shaking With CEL Came On
I used fuel injector cleaner in two different gas tanks; the car started shaking and the check engine light came on. The mechanic changed a sensor but the car was doing the same; I was told that it will take 4 full gas tanks to clean the gas lines. I went to autozone and they told me that the car had a misfire on cylinder 5 and multiple misfire as well. I do not trust the mechanic any more since I had to take the car back to them several times and still is not fixed. They also did a full tune up and the check engine light still on and flashes when I am going about 55 mph.

I'm working on my 99 f-150. I replaced all my spark plugs and coils after I got a misfire on cylinder 3 reading on the scanner. The truck was running ok but two weeks later it started to ride rough again I checked the scanner and got the same reading for a misfire on cylinder 3. Why its giving me the same misfire again? Could my injector cause that misfire? What about the egr valve?

I haven't started my passat for the winter and I finally did today. It was ruff start/idling and I pretty sure it was misfiring on one of the cylinders. I turned off the car and start it again...same thing, ruff idling like 3 cylinders were running. I waited five 5 mins and started it again, then it was a normal start on all cylinders. But the engine light came on, even though it started properly. I know I have to clear the code to get rid of the engine light. But I want to avoid any future misfiring. So I'm thinking new spark plug/coil overs.
View 9 RepliesCivic - Honda :: Rough Startup - Oxygen Sensor Gone Bad / Each And Every Cylinder Misfiring
This is a 2003 honda civic with about 150k on it. Recently the check engine light came on so I went to Advance auto parts to get my codes read. I got back that the oxygen sensor had gone bad and each and every cylinder was misfiring?
What could be causing the each cylinder to misfire like that? I drive it about 60mi every day and it doesn't seem to drive all that rough. So it's kinda weird that it said every cylinder was misfiring, like how could I even drive it like that?
I heard the oxygen sensor is something I don't have to worry too much about. I could still drive it. The clerk told me to some spray carburetor cleaner on it and that should do something for it.
But recently I've noticed that it starts up rough, seems to strain for about 2-3 seconds then it starts.
Camry :: 2005 LE 2.4 - Engine Runs Rough / Loud While Driving And Cylinder Misfiring
I bought a 2005 Camry LE 2.4 4 cylinder. It was rather loud while driving, but especially while accelerating. It had error code P0420 from the beginning. It had a completely broken torque strut which I eventually replaced. Afterward since it toned down the kicking from the engine, I was able to notice that I could feel and hear the engine kicking like a cylinder misfiring. The computer gave me error code P0353 (Ignition Coil C Primary/Secondary Circuit Malfunction) consistently, and only a couple of times gave me error code P0500 (Vehicle Speed Sensor Malfunction) which went away.
I swapped the ignition coil and spark plugs around but the error code would persist on the same cylinder. The spark plugs didn't look particularly worn but I'm not experienced on what bad plugs look like. The codes persisted still, but later on P0353 went away, and the obvious kicking stopped but it still ran with a lack of power and hesitating on acceleration along with a strong smell of fuel in the exhaust. I measured the resistance of each fuel injector and all measured the same. I removed and flushed each of them with cleaner, but same situation.
What do you think? I don't get the bad cylinder code anymore but something is clearly wrong. Bad fuel injector? Bad wiring harness? Bad compression or head gasket (maybe from the movement of the engine while the torque strut was bad)? Hopefully not the computer... And could the loud noise be related to this problem or is that probably just a cracked exhaust from when the torque strut was allowing engine movement?
Ford Ranger / B-Series :: 2002 - Rough Idle Codes / Cylinder 2 And 3 Misfiring
I have an 02 ranger xlt 3.0, it started having a rough idle, codes say cylinder #2&3 misfiring, changed plugs, wires, coil pack, didn't work, still same code, checked injectors on right side, all 3 had ohm reading of 15.8-16.5, the injectors were clicking like they are supposed to, sprayed carb cleaner around the intake ports, didn't change the idle at all,what else can I check or do? with out tearing the engine apart, unless of course I have to, the truck has been very good to me, it's got 205,000 miles on it, I need it to last at least another year...

Ok I got this truck from my mother-in-law for free with a blown head gasket cylinder 6 driver side. I did the replacement had the heads machined put it all back together by the book. Now I can't get it to fire on all 6 cylinders only 5 I think. Thought maybe bad gas (it sat since late November) put 5 gallons (over double the gas) fresh gas and half a bottle of b-12 chem tool. Dubble checked all plugs wires connections (coils plugs wires all new). I drove for about 10 miles oil pressure and temperature stayed perfect but no change in running truck shakes a lot and no real power. Don't sputter or backfire no engine codes other than imcr bank 2 open. Engine is 4.2l v-6 170k miles.

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.
Santa Fe (CM - 2007-12) :: Quite Rough Ride / Not Smooth?
I have a 2011 Santa Fe - I have noticed it is quite a rough ride. I guess I am used to the suspension in my Passat, but I still find it is not as smooth as it should be. I thought maybe giving it a bit of time would work, but so far at 25,000km it is still the same. Find it's a bit of a rough ride? Or should I look into it?

I took it to a local parts store who put an analyzer on it an it showed the #3 spark plug was misfiring. I am hoping its the plug. I do my own work but havn`t been able to find a correct sequence to replace the plugs.
View 3 RepliesLexus LS 2007+ :: Rough Ride - Squeaks On Every Bump Hit?
I have been experience some rough ride, and i am always in "comfort" mode for the air suspension. I have been changing the suspension over to "sport" for a mile or two then back into "comfort" and that seems to fix it for a day or so and then it goes rougher again.
I have also noticed when i am riding with the windows down that every time i hit a bump not only is there a jarring jolt, but also a squeak almost like a shriek that comes from presumably the suspension in the front ?
I would like to know if this is a sign of failing air bags, a bad compressor, bad sensors or even if the control arms are in question at this point. . .?
Ford F-150 - 1997-2003 :: Truck Randomly Started Missing - Misfire On Both Cylinder 1 And 8
I've got a 97 f150 4.6 that has randomly started missing over the last month. It has started to get more frequent and codes are showing a misfire on both cylinder 1 and 8. Both of these cylinders run off the same coil pack. I'm thinking its the coil? The plugs and wires, motocraft, have about 3k on them and the truck runs great otherwise. I just don't know how common a coil would cause this or if they would act intermittent like this.

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.
View 2 RepliesPhaeton :: Getting Judder In The Ride - Misfiring Petrol Engine
I've been getting some judder in the ride when my 3.2l V6 petrol engine is under load at low speeds - usually around bends or uphill.
My VW main-dealer diagnosed this as a slight misfire - not enough to bring on the check engine light. They checked the coil packs and the sparks have been replaced - no problems with either.
They then checked the compression on all 6 cylinders - and apparently Cylinder 4 is running at 7.7 BAR and Cylinder 6 is running a 14.3 BAR. Compression 'at new' would be around 13 BAR and anything below 7.5 is considered 'wear'. Pressure on the other Cylinders varies between 11 and 9 - see below:
Cyl 1: 11
Cyl 2: 11.4
Cyl 3: 10.8
Cyl 4: 7.7
Cyl 5: 9.3
Cyl 6: 14.3
I can't see how I could be getting MORE compression than 'at new' on one cylinder and so much less on another. I also have a feeling that the problem is worse when petrol is low... Engine has only done 75k miles and has full VW main-dealer history. Have tried the old 'Italian tune-up' with Forte engine additive - no change. A knowledgeable friend has suggested it might be the Hydraulic valve lifters sticking..
Touareg :: Exhaust Malfunction Light - Choppy Ride / Engine Hesitant And Misfiring
When starting my T-Reg leaving work yesterday, the yellow exhaust malfunction light (located in the rpm guauge -- it looks like an engine but the manual refers to it as an exhaust malfunction) came on and would blink now and then and remain on.
I proceeded to drive home and the entire ride was choppy and the engine was hesitant and misfiring. When I arrived home, I turned the Reg of and then back on again and the light never came on. I drove it around the block and it was fine.
We have been experiencing tremendous cold weather in the Northeast (-20 to -30 with the wind chill). Reg started fine this morning, no light. Was this a function of the computer resetting itself?
Ford F-150 - 1997-2003 :: Truck Suddenly Started Running Rough / Too Many DTCs All At Once
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?
Ford 6.0L Power Stroke Diesel :: 2005 Missing / Truck Started Running Rough
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.
Ford F-150 - 1997-2003 :: 1999 V8 Will Not Start / Truck Started Idling Very Rough And Died
1999 Ford F-150 V8 5.4L... The other day I was attempting to fix my 4wd. I discovered that the vacuum tube by the 4wd solenoid had become disconnected. I reconnected it and in an effort to see if my fix was successful, I drove my truck up one of the canyons nearby. I got to an area full of loose rock and popped my truck into 4wd. As soon as I began to drive, the truck started idling very rough and died. I attempted to restart it for the next few minutes unsuccessfully. I got it started once and it continued to idle rough for a few seconds and died. I have not been able to start it since. It turns over but will not crank. It is not throwing any error codes. What I have checked so far:
Spark plugs are working.
When turning the ignition into the ON position, I am able to hear the fuel pump working.
I have not seen any cracks in the vacuum hose.
All the fuses are still okay.
What the culprit may be?
Ford 6.0L Power Stroke Diesel :: Rough Running / Truck Started Bucking And Hesitating At 45 MPH
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?
