Repair :: CEL / VSA Came On Again - Cylinder 3 Misfire?
Aug 7, 2015
My Honda's check engine light and VSA light were on. The diagnosis was cylinder 3 misfire, an apparent Honda problem and one that I've had fixed once before on this same car at the dealership where I bought the car. This time the tech said I needed the pistons replaced and that the damaged pistons had also damaged the cylinders so they needed to be repaired (not replaced), and that I needed new spark plugs. My car has been in the dealer repair shop since July 16 (3 weeks today). I've had cars in the shop before and know just a little about cars. Three weeks seems like a LONG time. My question is: Is this normal or not (I am a woman and I'm not sure the tech/dealership is being honest with me. They assure me that this repair can take a long time).

I have a 2005 SEL Freestyle with 114K miles. Cyl #3 missing. Has all the symptoms of a "lean misfire" - reading the code said #3. The indy mechanic already replaced the spark plug and the coil. Misfire still a problem. Tried to put some cleaner in there which did not work. He thinks the head needs to be replaced ....
The a/c is also busted. Needs a compressor. Not to mention I'm probably looking at brakes before much longer.

I recently purchased a 03 Camry XLE V6 love the car, but the engine has been giving me trouble. Since owning the car in January it has been in the shop 3 times for a cylinder misfire on 5. They jave replaced the ignition coil, spark plug, and fuel injector and still would misfire, it might be a few weeks later, but it would still misfire. It is currently in the shop for the something, they have checked the fuel, electrical system, and compression tested the cylinder and all has comeback good.

I have an 03 Lincoln LS V8 136000 miles. Just bought it in mid June and it was throwing P0420 and 430. I changed out the Coils and plugs and that seemed to do the trick. Before I was getting about 18.5 mpg and after it went up to 22 mpg. Well this lasted for about 250 miles (about a week). Now I have developed a really bad miss on #7,and a sometime flashing CEL, changed out the coil, no change. My question could this be a fuel problem? I did have one thing strange thing happen before I did the coils and plugs. I was just pulling on to the on ramp stepped on the pedal and it was like some one turned the car off nothing let off the gas and it was still idling tried again nothing, pulled off to the side. turned it off and restarted and it was fine??? Plus the fact it seems now that I my have to do the solenoid in the tranny grabbing during shifts.

Just today I acquired a 2005 Prius (trim level 1... so no options at all) in exchange for a cruddy old Ram truck and a dying Avalon. They had issues, but so does the Prius. The car has around 218K on it, I just replaced the spark plugs with NGK iridium plugs, cleaned the MAF, sort of cleaned the throttle body a little bit, and even swapped the coils around to see if the misfire would change. I also gave the car a new air filter.

I am having a misfire code on the #1 cylinder. Its not bad but I really want to nip it in the butt before it goes out completely. I was told to try and get some of the older style coilpacks that bolt on and go with them. Can I put them on my 03 passat 1.8t.

Getting misfires on cylinder 1 and 5 in my 2001 Jetta GLX. Replaced coil pack. Installed a different/used cam position sensor.
Swapped injector 1 and 5 with 2 and 6. Cleaned MAF and throttle body and did adaptation. Checked resistance of plug wires and swapped plug positions.

She is really running rough. Vcds engine scan shows no value on bank2 of the O2 sensor or lambda once I drill down into things. I haven't been able to figure out much else. Also I was getting a fault for a misfire cylinder 3 so I replaced all the coils on that side of the engine and put in a new set of spark plugs all around which did improve things but the car is gutless from idle to around 2000 rpm then it starts to pull. The check engine light blinks for about 30 seconds and then comes on steady. I used a propane tank to try and find any vacuum leaks but everything looks good so far. I guess I will take it to my independent shop hoping his scan can shed some more info on the O2 sensor readings.

I had my car tuned over the weekend with apr stage 1. As soon as I went to start the car to leave I started getting a misfire on cylinder 4. We have tried swapping coils around and re-flashing the ecu with no luck.
Details on the car : 2010 GTI 6spd 21,000 miles

As the title states... 2003 Passat 1.8T. The car was running fine. Had a new timing belt installed. The Check Engine light now continues to come on for Cyl #1 misfire. Attempts to fix so far include:
1) New plugs
2) New coils
3) New injectors
4) new cam and crank sensors

So, my 2014 Tiguan started having a misfire on cylinder 1. It has 35000kms with 80% highway. I have an APR stg 1 tune. The misfire started at 30,000 or so. I took it to the dealer and they said I would have to get the tune removed before they could look at it... I did some trouble-shooting on my own. Moved coils, stayed on #1. Replaced coils. It came back. Changed plugs, stayed on #1. Drove three hours to get the tune removed and back three hours... The whole week the dealer has been hesitant to say they will do anything on warranty. Spent most of their time trying to prove my changing the plugs and coils caused the problem. Finally, yesterday they put a call in to VW Canada who agreed to change the injector and manifold. The dealer called to say I need the carbon cleaning done. Of course I do... I agreed to it but asked for pictures. I change my oil every 5000 kms and drive almost all the time on the highway.

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.

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.
