Ford Excursion :: 2005 V10 - Cylinder 4 Misfire
I recently purchased a 2005 Ex 6.8L V10 and I have been struggling to figure out the Cylinder 4 Misfire for close to 3 months. First thing I did was replace all 10 spark plugs with Motocraft plugs. Check engine stayed away for a few weeks... then came back. I next replaced just the #4 coli with a DG508 Motocraft coli I picked up at O'Reilly's. Again the check engine light stayed away for a few weeks.
Finally, I cleaned out #1-4 fuel injectors and swapped positions of #1 and #4. This time the check engine light stayed away for over a month. However, it just came back today, and again, it is #4. I am now at a loss for what to do. I assume it is not the fuel injector since I swapped the #1 and #4 injectors. If I have new plugs and a new coil pack, then what am i missing?
Subaru - Forester :: 2005 CEL Blinking With Cylinder Misfire
My 2005 Subaru Forester just passed Rhode Island inspection last week. I didn't use for 6 days. Last night when we got home I moved the car and noticed a strong gas smell. This morning on I drove it cold on way to work right away I noticed lack of power at low gear (its automatic trans), a jumpy idle, and some smoke out back (not too much and looked whitish). Check engine light flashed a couple of times but didn't stay on nor flashed continuously. I know flashing CEL is BAD, so I went right back home and parked, didnt even drive a mile.
I'm thinking some sort of cylinder misfire.
Avalon 2005-12 :: Misfire Code For Cylinder 4 On 2006 Toyota
I experienced a misfire code for #4 cylinder on my 2006 Toyota Avalon approx 8,000 miles ago and replaced the three front bank coils with Beck/Arnley coils. I didn't realize they were made in china until they arrived. The car ran fine until today when I got another misfire code for the same cylinder. I still had the two old coils in the garage so I swapped out # 4 and I'm happy to report that solved the problem. My question is should I be concerned that the # 4 cylinder has gone thru two coils in 8,000 miles or chalk it up to cheap chinese crap replacement parts?

I have a 2005 Hyundai Sonata 4cyl. and have a misfire problem with the 1st cylinder. I've had it pressure checked and there isn't a problem with the cylinder, such as a ring or warping problem. I've replaced the wires, both boots, both ignition coils and the plugs twice. I was told I need to replace the ignition coil again but I wonder if there is something that is making the coil go bad. I've also replace the throttle position sensor and both O2 sensors. I had the front catalytic converter replaced because it was bogging down and very slow. It still runs rough and the check engine light is on. I was told also that I need to replace the engine speed sensor. I bought the car in Oct. of 2004 and only has 68000 miles on it.
View 2 RepliesSaturn - Cylinder - Vue - Misfire :: 2005 - Steady CEL Code P0300
2005 4cyl. Vue with 54K... Steady CEL. Runs great. Absolutely no problem accelerating. Don?t hear or feel any misfiring. There is a slight rumbling sound when I first start to drive the car, but to me, the sound doesn't seem come from the engine, but rather underneath the car. It goes away when I continue to drive. Since winter began, I occasionally feel a very slight hesitation during idle?happened once or twice lately.
Again, I only feel justified in mentioning it simply because of the codes that were generated. None of my passengers have made a comment about the idle or the drive. My friend, however, made a remark that occasionally, there is a very very very slight hesitation at the downshift when braking. No crack in gas cap. Great fuel economy. No problems accelerating at all. Never hear or an actual misfire, which I take it, means a problem when accelerating, a jerking, or popping noise.
Took it to a dealer. Codes were 0300, 301, 302, 303, 304?302 generating most often. Dealer recommended new ignition module and plug replacement, but they said it wouldn?t be a guaranteed fix and that it may need EGR replacement (don?t hear knocking though) or be a burnt valve in the cylinder. No suction out tailpipe, no rotten egg smell (signs of burnt valve). What are the chances of burnt valve in a car with 54K anyway?
Also, my maintenance schedule claims that I don?t need new spark plugs until 100K. Is there anything else this could be such as a dirty injector system, fuel filter, fuel pump, or air filter? Again, overall, the car runs GREAT! Should I just wait and see if the misfire becomes more pronounced so when I take it to a mechanic, they won't be looking for a needle in a haystack?
Avalon 2005-12 :: Various Misfire - Common Code P0301 Which Is Cylinder 1
'07 Avalon with 169k miles. I replaced all 3 back coils and 6 plugs back in December when I had various misfires, but the most common code was P0301 which is cylinder 1.
Car ran great until last week when I made a hard left and accelerated. CEL started flashing, read code and it's P0301. Every time I accelerate half throttle or more I can set the code off, but then shutting down car and restarting it drives fine, until I go half throttle. Car runs better when cold, and worse when I turn left and accelerate.
As long as I don't mash the gas I can drive for a half hour or so without the strumbling/hesitation. Surely the new coil hasn't failed so soon, I hate to pull the wipers, plenum,etc. and buy another coil just on a chance that might solve the issue. Car is only throwing a P0301 this time, no other codes like before. I've read a clogged cat or sticky exhaust valve could cause a cyl misfire.
Ford - Taurus :: 2005 Started Running Rough - CEL Came On / Cylinder 5 Misfire Detected
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 2005 f150 with 96,000 miles. Long story short, last August I was headed to the mountains going up a steep long hill and the engine light come on. once i was over the pass the light went off. During my 4 wheelin' trip it never came back on until I was headed home and going over another pass and then it stayed on for a couple of days. I had it checked and it was a cylinder 5 misfire. I did some research and found that replacing the coil cover might fix the problem and if not the spark plugs would need to be changed.
I changed the coil cover, problems solved... until I headed to the mountains. light came on and then eventually went off later that day. I didnt think much of it. then a few months later i was headed to the mountains again and the light came on in the same place on the steep incline hill. I. took it back to the shop, same reading. I decided it was time to replace the spark plugs anyways so I would invest. I have new plugs and everything is good however, I had no plans to go to the mountains in the near future. Now, a few months later I headed to the mountains and crossed my fingers it would not come on but it did.
I've done the research again and it seemed like the coil cover and spark plugs are usually the cause of the problem...however I have changed mine. The light is now off again. I don't understand what is triggering the problem and what is really happening and if it is safe to keep taking to the mountains with this happening. I did notice that everything was fine at 60MPH but once i hit the hill and steeped on the gas to go 65 and hit 4-5RMP that is when the check engine light came on...
Ford F-150 (2004-2008) :: 2005 - Cylinder 5 Misfire - Spark Plug Replacement?
I am getting a cylinder 5 misfire and this has been a "on again off again" situation since last August. I took it around to a few places and the general solution was to get new spark plugs. After doing a bit more research I was advised to change the coil cover. I did that and it fixed the problem. Then about 4 months later the light came on again. I happened to change the air filter and the light went off. I though great, problem solved! not so much, when i went to the mountains the other day the light came back on. I did my research again and I have decided to get the plugs changed. Its a 2005 f150 with 94,500 miles on it.
I am told its time to change them regardless. I started calling around and getting quotes and have been told by multiple shops that ford made the plugs in my truck in a bad way. They have been telling me to change them and breaking them is a 50/50 shot. THEN, when they quote me they charge a rate to replace them plus the plugs themself. If they happen to break one then the customer pays for the new one. Do the plugs would really break that easy and should I plan on replacing some of them?
Ford Super Duty (1999-2016) :: 2005 F250 - Code For Cylinder 3 Misfire
My 5.4 F250 with 200,000 miles having many problems... It all started a few months ago, when the cam needed to be replaced, and a cam phaser was also replaced at the same time. It ran fine after, then threw a code for cylinder 3 misfire. The guy I took it to said it was due to the huge crack in the exhaust manifold and that was messing with the o2 sensor coming up as a cylinder 3 misfire. So, got the new manifold and it was good for a few weeks.
Now, starting the other night, Friday the 13th, it threw a CEL when I was coming into the driveway. It had been throwing a code every once in a while, and I brought it to school to scan it Friday the 13th but there was no code. So, I assume that it is an intermittent problem, no big deal. When I go to get in my truck to go to work a few hours later, the 5.4 cranks... and cranks... and cranks.
I get it to fire up, and it dies again. Run codes, and it says that the cam positioning sensor is broken. Replace both of them, still acts up ie. doesn't start when it does start it runs very rough and stalls. Get it up to my uncles shop, and replace fuel filter.. Still runs like trash. Run codes now, and it says rich/lean in bank 1.. My uncle tells me to move my truck out of the shop, so I start it up, and it runs great. No hiccups, it idles perfect as I move his truck out of the shop first.
I park my truck outside and let it idle for about 10 mins, and when I come back out it is still idling, perfectly fine. I get in, put it in reverse, and get about 20 feet when it dies and will no longer start back up. What could be going wrong?! Sick of throwing money into this thing! At one time while started up in my uncles shop, it was blowing black smoke, as if it was a diesel!
Prius (Gen 2) :: Misfire On Cylinder 1
Its not the spark plugs or the coil. What else?
View 3 RepliesPrius (2004-09) :: CEL On / Misfire On Cylinder 1 Came Up
I bought an 07 gen 2 a couple weeks ago. A couple days after I got it home the check engine light came on. I did a scan, it came up, misfire on cyl
1. I installed new iridium plugs, switched the no. 1 igniter with no.
2... code came back misfire cyl 1 again.
I then did an ohm check on the injectors which were all spot on, then ran the engine and listened with a stethoscope to number 1 injector and could hear it clicking. Next thing I threw a can of Seafoam into the gas, drove that tank out and then threw a can of injector cleaner into the next tank... I forget the brand.. it's that stuff they've been selling for a hundred years that has MEK in it.
Anyway... I cleared the CEL and it's been a couple days and about 50 or 60 miles without a re-occurrence. I'm wondering if this is a common problem with prius's? (I know... but I refuse to use the word Prii... it just bothers me) Because the engine is always under such a light load, I'd think it would be prone to carboning up and such. Also... if this light comes back I'm thinking the next thing I'll do is switch number 1 and 2 injectors to see if the problem follows it.
Prius (2004-09) :: PCV Can Cause Cylinder Misfire?
I have a 2005 Prius with 135K miles on it. and last time I change my PCV was 55K. today, my car is misfiring in cylinder. My mon has a Nissa Altima and did not change PCV since day one and one of the Cylinder was misfiring one year ago. My brother change the PCV valve for the Nissan and reset the ECU and no more misfiring. I am wondering if I should also change the PCV valve for the Prius to fix the misfiring issue. and Why is a bad PCV valve cause misfiring.
View 10 RepliesPrius (2004-09) :: Intermittent Misfire Cylinder 1 Code
I posted this problem several months ago about a p301 code that my 2007 Prius has been generating. I eliminated all the easy stuff... plug, spark unit, fuel injector. Over the past year since I've had the car, the CEL light has gone on for a couple months then shut itself off for a couple, then back on ... probably has shut itself off 3 times in the past year, each time staying off about a month or two before coming back on. Some background on the car, supposedly the PO hit a rock and damaged the motor about 2 years ago and had the short block replaced.
Anyway, the CEL has been on again for about a month, and I got a notice for Illinois emission testing, so I decided to take it in to the dealer and have him do a diagnostic so I can get the emissions passed. After an hour and a half of testing they told me that the best they could ascertain, the car has been submerged in water, as there is a lot of rust in areas that never get any rust, and they think there's a short somewhere.
The service manager at the dealership said if it was his car he wouldn't spend the money for another 5 hours of trouble shooting, and if the car runs good he'd just drive it as is. They cleared the CEL and the service manager just charged me for an oil change as they caught a recall on the steering that hadn't been done and figured he'd let me slide on the hundred for the diagnostic.
Prius (2010-12) :: Code P0304 Misfire On Cylinder 4
Well, I have a big problem on prius 3, the problem is that it has a big and I mean a big body shake when I decelerate above 30 mph or slowly accelerate above 30 to 50-70 mph, when I fully accelerate, the body shake disappears. When the body shake occurs MIL comes blinking and DTC P0304 comes but not always, but the shake is only when the coolant is hot.
On the other hand, if the MIL is not on with the tester it can be seen that the cylinder 4 has misfire margin, only cylinder 4, every time. Now what I have done is to exchange the injectors, problem remains on cyl4.
-replaced the coils, problem remains on cyl4,
-clean the EGR, problem remains on cyl4,
-opened the engine to see the valves, cylinders, pistons, exchanged the ring set,problem remains on cyl 4,
Replaced the wheels, the problem is still there, now I want to replace the drive shafts.
Prius (2010-12) :: Check Engine Light On Due To Cylinder 1 Misfire
I plugged in a OBD2 reader and its show misfire on Cylinder 1.
I haven't driven the car for 4 days, and when i started the engine this morning, the engine show knocking when the regular engine kicks in (rough). i will be bringing the car in tomorrow (dealer). my car is a 2011 with 16k miles, strange for this to happen so early in age.
Prius (2004-09) :: Misfire On Cylinder 2 And 4 - Car Severely Idle Rough
I own a 2007 prius, it has about 320,000 miles. It has recently been diagnosed with a #2 and #4 cylinder misfire. The car severely idles rough, but when getting in the gas it goes away. I have replaced the spark plugs, the old plugs were very white(lean), replaced fuel injectors, used fuel injector cleaner. I've sprayed carb cleaner around the intake to see if I might a leak--no leak. The motor uses about a quart of oil every 1,000 miles since about 100,000 miles. I'm just guessing, could it simply be low compression causing this? I pulled the new spark plugs after about 5,000 miles and they where white also.
View 9 RepliesPrius (2004-09) :: Misfire On Cylinder 1 After Changing Radiator Coolant
I replaced a failing two way coolant valve and went ahead and replaced the coolant. After this the heater wouldn't get hot, so figuring there was still air in the system I added more (which it took)...and repeated that twice. (and opened the top valve to allow it to bleed). Finally heat.
I got up this morning and the heater still wasn't working....so I added more fluid....which it needed. Now I have heat.
BUT, The engine started running like crap. Code says misfire on cylinder 1. Changed the plug and coil pack. This did not work. (When I pulled plug one out the end of it was dry.)
Could it just be a crazy coincidence Immediately after I changed the radiator coolant that a faulty or clogged injector rare its ugly head? The car was running fantastic before this. I thought, before I check the codes, that some way maybe I overheated the car and landed with catastrophic issues.
I have 378,000 miles on my 07 pruius
Prius (2001-03) :: Cylinder Misfire P0300 - Error Has Been Occurring Almost Daily
General misfire when the engine light comes on. This error has been occurring almost daily, sometimes it pins it down to cylinder 3. My wife's nephew who is a mechanic says it could be the sensor, but I have only been getting around 30 mpg though the car seems to run alright. I did go ahead and get the plugs replaced, as I was told it could be a bad plug but the error light still comes on as before and the mileage appears no better. What could this be? I am retired on fixed income and dread the very idea of an expensive diagnostic & repair session with a dealer service. Their solution for about everything wrong has been to replace the gas tank (three times already in the life of the car). Last time that did not fix what was going on with the car..
