Lexus ES 2007-12 :: Ignition Coil Malfunction - Misfire In All 6 Cylinders?
Sep 18, 2010
Started up my car the other night and my engine light came on, trac light came on... VSC msg came on the dash, engine was rough idling. I drove it home after checking my fluids... i took the OBD scanner to see whats going on, hoping i just need a battery change. Codes popped up P0354, P0300-0306. basically ignition coil malfunction, and my cylinders were misfiring.
I am at 62k miles and warranty crapped out at 50k. the problem was obviously electric, since all 6 were misfiring, otherwise it would only be a few. I haven't had any engine work, I just recently did a proper oil change at home(royal purple 5W30), which I've done since I've had the car in 07.. I took the car to the dealership for the CPU reprogramming for the recall in April.
About to take the car back to get it checked up on and fixed.. I am lowered on coilovers and 20" rims, which gives it a rough ride, but i dont think it would cause this problem. i dont track/race the car and i drive it relatively civilized. Lowered since 30k miles and 20"rims since 50k miles.
What could've gone wrong? timing off etc... i pulled my engine cover to check the connection points for the coils, all seems fine, no corrosion on the grounding points. i was only able to check the front 3 coils, the other 3 were hidden in the back and i wasnt able to look at them. i assume they should be fine as well..

I do not know the 5.4l 3v as well as my last 360ci dodge. It's a 2005 F-150 SuperCrew 4x4, got it cheap, and it's got issues. Got codes for misfire on cylinders 4 and 5 and Coil 'D' circuit malfunction. Obviously it has codes for limited power as well. was wondering how cylinder numbering goes and what coil is 'D'.

I'm getting Codes: P0300-306 (Misfires) and P0356.
I have researched the definitions of these codes and see that P0356 indicates an ignition coil failure on coil "F" (which would be Cylinder 6?)... but how is it possible only one coil is failing but I'm getting multiple/random misfires on all cylinders?
I've looked at the wiring diagrams and the only place that I can see a "single point failure" that can cause such a thing, would be the ECM itself...

I have a 2007 RX 350 2WD. Recently, the check engine light is on, as well we two other lights are on as well: VSC, TRAC OFF.
I went to Lexus and was told that the error code is P0356. I was told that the ignition coil F is problematic and need replaced. I was quoted 1 and 1/2 hours two 2 hours work and need $412 for the repair. Well, I went to auto zone and was told that No 2, 4, 6 ignition coils were on outside so that it would only take about 5 minutes to replace the problematic one with a new one.
I did the replacement indeed by myself after buying a new ignition coil. Initially it was fine and the light went off after a little while. However, after about 10 days, those three lights went back again. I check the ignition coil, it seems fine and I was told that it is very unlikely for a new ignition coil to go bad this quickly.
I was told that I may need to check my spark plug as well. BTW, when I start the car, the car is a little bit shaky.

What to do Misfire Error all cylinders also coil code P0356 . It is 2006 Avalon Ltd with 37,000 miles always maintained and all recalls completed. Is there something I missed or is this for real or could there be a common problem that is causing all the errors. Car idles ok and no problem driving below 60 mph anything over and you can fell a shutter like it will lose power.

I just completed the spark plug change on my wife's '07 RX350. As the numerous threads on this topic point out, this is one serious undertaking. I'm not claiming to be a mechanic but have done my share of DIY's including changing the usual oil/filter, brake discs/pads, serpentine belt, rear hatch switch and now the spark plugs on my wife's car and the same or similar on all of my other cars. This has got to be the single most difficult project that I've tackled recently. I did fail to do the front Mac struts but this was because I didn't appear to have the right spring compressor. Go figure.
Anyhow, I found that I needed to remove the front windshield cowl to get access to that infamous third stay bolt.
To my question ... I managed to break off the tabs that lock the connector to the ignition coil on about three spark plugs. I'm concerned about these eventually vibrating off. Should I be concerned about this? Do I need to now go in and change these? Or, tie-wrap then in place?

Started this winter as a misfire on random cylinders. I replaced all apart plugs and verified the gap. Replaced all the coils. Still occurred during the cold months. Once it warmed up it went away for a short while. The only codes present at the time were random misfire codes. Took it to a shop and they told me the injector was bad on cyl 1. Today I replaced the injectors with a matched set of 4 matched flow Denzo remand. Ran it on the TIS tech tool and was given a barrage of codes. I can unplug #1 coil and it will smooth out and stall within 90 seconds. Engine runs rough. Intake was just done as well. From Toyota TIS
P3191 – engine didnt start
P3000 - Battery Control System
P3101 – engine system malfunction
P3190 – poor engine power
P1300 - ignition circuit malfunction #1
P0303
P0302
P0301
P0300
c1259 - ABS error code meaning problem with regenerative braking. Probably caused by me forcing the car to recharge the HV while misfiring. HV battery was getting dangerously low from sitting for the last 6 months.

My wife's 2011 Volkswagen Jetta (2.0 I believe) is misfiring again. We took it to the dealership about 6 months ago and they said that the ignition coil had gone bad. They replace the ignition coil and said that the plugs needed changing as well. I went to Auto Zone and got some decent plugs and changed them myself at home without much problem. It seemed to work with the problem (although it didn't seem to completely fix it) for a while, but it just recently went back to misfiring. The current symptom is that it seems to misfire when the car is warming up, but misfires less when the car is warm.
The dealership says that the plugs that we got were not recommended by the dealer (they recommended Bosch) and that they need to be replaced. I think this is BS and it is not going to fix the problem.

The 2005 Avalon has 48K miles and it's been running well without any issues, until today.
Driving in city traffic, max speed is about 30 ml/h, The "Check Engine" light and the "VSC (Vehicle Slip Control) Off" lights came on. I did stop the engine, restarted after couple of minutes and the same lights stayed on. The car ran just fine, no noticeable difference in performance.
With the OBDCOM reader, the Avalon has this code:
P0351 232
P0351 Ignition coil A primary/secondary circuit malfunction
That seems to indicate a malfunction for cylinder A, or #1, ignition coil that has nothing to do with the "VSC" AFAIK. Is this a misread by OBDCOM reader, or the Avalon is confused?
The code had been reset via the OBDCOM reader, the car runs fine, neither of the lights come on now. Should I do something about coil A, or just wait until the code comes back?

So my check engine light came on a few days ago and I went down to Autozone to check it out with the code reader. The result was "Cylinder 4 Misfire" (the guy said that was as far as the diagnosis would go...) and since I just replaced the spark plugs under 1,000 miles ago, I figured it must be the ignition coil (I replaced coils 1, 7 and 8 about 100 miles ago too).
When I removed the coil, the outside was fully covered in rust, the spring had a tiny bit of rust, and it smelled a little like gasoline. After replacing the coil, the check engine light went off, however the engine still runs rough and doesn't sound much different than before.
What the issue might be? Would a compression test or a better code reader diagnosis give me more insight? I live in Louisiana where we get a decent amount of rain and humidity, so I'm worried there might be a moisture issue down around the spark plug. Also, the exhaust seems hotter than normal and the engine gets pretty hot in a short amount of time.

Understanding all the needed parts when replacing ignition coils on a honda fit 2007. My understanding is it is best to replace all 4 (are there 4 total?) as well as the spark plugs - also 4?What other parts are needed, does this car require spark plug wires?
Basically, Would this be a good time to replace air filters as well? Car has 116K miles.

We bought it in 2010, since then we have replaced 5 ignition coils and 2-3 batteries. Everytime the car acts up, the VSC and traction lights come on and the car starts stumbling and hesitating. The car eventually dies within a few minutes. Pull up codes and its always been an ignition coil.
Well we had all of these covered under warranty until the warranty expired in Aug. A month ago this happened again, and thought the battery was dead. It ended up being #4 coil, so I replaced.
My wife drove last week and lights came on and lights started going on/off and dinging at her and the car died. I jumped it to get it home, turned off the car and was dead. Voltage at battery was 9 volts.
I charged overnight and started the next day. I pulled negative battery cable w car running to check alternator and it stayed running, so that's good. The car is now starting just fine again.....until this happens again.....which it will.
My question is what in the heck can be making all of the coils go bad and why is the car intermittently throwing warning lights and just dying? This last time the codes pulled we P0345, PO365, PO390. All of which I don't see an explanation for.

2007 Passat 2.0T ... I just purchased this vehicle and after about two weeks of driving it has gone bananas. I found a ton of oil in the spark plug holes, and installed a new valve cover gasket...It no longer leaks. I am getting P0171, P0507 codes and multiple misfire codes from all cylinders...

I am getting P0355 error code and potential misfire codes on all cylinders. Engine light and VSC stays on now. Idle is unstable and power is a little jerky at times. I bought a Denso direct ignition coil to replace, however, Cyl 5 looks difficult to access.

I have a 2008 RX350 with 68k on the clock. Received a check engine light for random misfire (P0300) and misfire on Cylinder 4 (P0304), Cylinder ,5 (P0305) ,Cylinder 6 (P0306). Question is what will be causing this to happen. I thought about changing the spark plugs to see if this is possibly the cause. but what else should i be checking?

I have an 07 kia rio, I had a misfire in the 3rd ignition cylinder. When I opened it it had oil in it. So I cleaned it out and put a new spark plug in it and change to a thicker oil. A few hour later wet to drive it and after five minute the car shut down. When I was able to get it to turn on, it started to knock. I got it check and said misfire in the 1st cylinder, So I changed out all the ignition coil one by one it didn't work till I got to the last one, the knock went away for a few minutes then came back. So I put the originals back it and the knock is gone but it still misfiring with the check engine light flashing or staying light.

97 SL ATX - Not firing on cylinders 3 and 6; no voltage to that coil.
I've checked:
Plugs
Wires
Coils
PTU
ECU
Timing
So I guess the CAS is the next best guess. So where exactly IS the CAS...and how do i test it? Also, where is the timing mark on the crank pulley? Cams are all aligned but I didn't see a mark for the crank and don't know where I should be looking.

Have a 2006 Ford Taurus that has two dead cylinders. Cylinder 3 and 4. Code says bad coil. I replaced with new coil and plugs. Same problem. Replaced wires and same problem.
Car has 65K. What is causing both cylinders to be dead? Pulled wires off while running and no spark on 3 and 4.

I have an 02 accent with a 1.5L and it is dropping #2 & #3 cylinders. I changed the coil packs and still had no spark on #2 & #3. I checked the wires going to the coils and had no voltage feeding the coil packs.

Al right i have a 94 ranger 4.0 4x4 auto 186k ... The truck has new bosch double plat plugs gaped .054, new wires, MAF, TPS, FPR, O2 sensors, ECTS and I checked the intake air charge sensor and is fine ....
My issue is cylinders 4,5 and 6 dont fire... the coil is sending a spark, i can pull the plugs one at a time and watch them fire (strong blue spark)... All fuel injectors do not leak and spray a perfect cone out of all 4 holes and noid light test is good ...
The truck runs like crap back firing and no power under 4k and i can pull off all 3 wires for bank one and it make no difference and when i unplug the injectors no more back fire....
