Passat (B5) :: 2003 Misfiring - Ignition Coil Faulty?
Dec 17, 2006
I have a 2003 passat 1.8 and I just started having a misfiring problem. I googled it and ran across a 2003 press release that VW had recalled them. I am going to call tomorrow, but I did a little testing myself. Probably not the best thing to do, but this is what I did. I had my wife start the car and I pulled off the coils until I hit the one that didn't make the car shake any more than it already was. It is the second one from the front. I pulled the spark plug out. It is the original, but didn't look too bad.
My question is: How do you test the ignition coil to see if it is faulty or if it could be the distributor? The coil that attaches to the plug looks a little burnt around the rim where it connects to the plug. Its not an expensive part, but I don't want to go buying another one just to find out it is the main distributor or something else...

I am having issues with my everyday driver as of late. I developed a misfire and replaced, plugs, coils, plug wires. Misfire persisted so we replaced, injectors, fuel rail. The misfire still was there and getting worse so we checked the engine mechanically for any burnt or bent valves and it checked out fine. We completed a compression test and all cylinders tested within 5 psi of each other. We finally replaced the ECU and Cam Sensor and the problem still is here. We do not know what else to do. I have narrowed down the misfire to cylinder one. The injector is not firing on this cylinder. I know this because when you unplug it there is no change in the engines behavior. As stated earlier, injectors are new, but i switched them out just to make sure it was a bad injector. I tested the lead and the voltage was appriopiate.

So I went to a local VW in Milwaukee in March and they saw I was eligible for the Ignition Coil Recall. So they replaced that and the first time I started the car after they did that my car wouldn't start. This was the first time I experienced the problem. I told them and they tried and it started right away. However, for the past four months I've experienced this problem where when I try to start the car it takes awhile to get it started. It doesn't click it just keeps making that loud noise of trying to turn over. I went back to the VW twice and they said the ignition coil is not related to this and they wont do anything for me. My check engine lights been on all along too and they say I need a temperature sensor replaced. They don't even know if this will fix my not starting problem. After spending a little time trying to start my car it eventually starts every time. Checked battery- its fine. Not sure what to do here.

Found out today that my third ignition coil is bad, it's a Honda civic 03' my question is, do I have to buy a new ignition coil. I had a clerk tell me I could switch the coils and it would run fine? Is this right? could I just switch the ignition coil with another ignition coil? This doesn't sound right. Well If I do buy new one which would be the third ignition coil? is it counted from left to right or right to left? Are there any telltale signs of a bad ignition coil on sight?

I have a 98 1.8T passat. The number one cylinder won't fire, according to my checks, the ignition coil is not being activated by the CPU, (no current at the connector only ground) what could cause this problem. Any way to check the crank or cam sensor.

Can a problem elsewhere in the system cause ignition coils to go bad? I have an '03 Mazda 6s, 147k miles, owned it since new (Dec '02). 3 1/2 ~ 4 years ago, over a period of 6 months I had to replace 4 of the 6 coils. A month ago, one of the replaced coils went bad so I had all three rear bank coils replaced (cheaper to do all three at once rather than one at at a time since half the engine needs to be disassembled to get at them). This week, I started to get the initial symptom of a coil going bad on me: Occasional stuttering in the engine.
This issue always starts when it's wet outside. The first few times it started when going through a car wash, this last time was right after Super Storm Sandy dumped a lot of rain (I am not in one of the flooded areas, NH just got a lot of rain).

Having issues with some or all of the coil packs going bad? Because it looks like all 6 coil packs on my R32 went bad...
Brief history, my car stopped turning on about a month ago, it was working just fine when one day when going to lunch it stopped wanting to turn on, I had to crank it about 3 or 4 times and it turned on, I went to lunch then got back but when I left for the day (at work) I once again didn't want to turn on and that's about it. I had to tow it home and a couple of friends and I began trying to figure out why we tested the fuel system and electrical. We could get no little to no spark on all 6 coil packs. Ran vag com and nothing would come up, I tested the Crank position sensor and it tested fine but broke the connector so I replaced it with a new CPS. Still, would not start.
So after a couple of days, we decided to try 6 known good coil packs and it fired right up. So yeah I've never heard of all six coil packs going bad at the same time, so what could cause that ? btw soon after the car started, about the 3rd time turning it off and on the starter decided to stop working, I'm thinking it was because of all the times I tried to start it, it was allotted. : thumb down

My grand am began shaking (shuddering) consistently yesterday morning and I ran a diagnostic reading on the car. It told me that there was a misfire. I replaced the spark plugs and still no change. This car has been a nightmare to do maintenance work on since everything is either within a case or impossible to access on a regular car jack - so what could be causing this reaction in the car? Is it definitely the ignition coil? I would just hate to attempt to replace that (not to mention the fact that it's $100+ for the part) if I didn't survey other options. 2003 Pontiac Grand Am 2.2....

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.

I was replacing my spark plugs and one screw holding the ignition coil stripped while another snapped. I have change 3 plugs (the easy one) and could have more problems. I spent half a day trying to drill the screws out to no avail and also noticed the intake manifold is plastic. I was thinking of swapping it out. This would alleviate the broken screw problem and make pulling the plugs easier. It also looks like it's just 8 bolts. Would swapping a new intake manifold in add any performance gains? Is there a manifold others recommend?

I am driving a 4 cylinder 2003 Hyundai Sonata just at 130000 miles. The other day on the trip back home the car started shaking violently and the check engine light came on. I ran the code and it led me to a cylinder 1 misfire. Today I replaced my spark plugs, and wires. The number 1 plug had some deposits on it, but nothing that should cause a misfire.
Now when the car is in idle there is a spark that jumps from the boot of one of the new wires to the grounding on the corresponding coil. I have never noticed this spark before changing the plugs and wires. It does this with either set of wires. I have a picture below where the spark is jumping from. The car has a noticeable drop in idle when it sparks. Do I need to look into getting some new coils?

I have a 2001 Accent GL DOHC 1.5L (which I believe is the same as your LC model).
One night it started running poorly - missing, bad acceleration - like it was only running on 3 out of 4 cylinders. It was missing whilst idling and would backfire and struggle to accelerate. I took it to a mechanic and they said I needed a new coil pack. So I bought a coil pack from a 2nd hand wreckers that looked pretty good, the car idled better but accelerated worse, like it was only running on 2 cylinders .
So I swapped it back to the old coil pack - and now it wont even start. The engine turns over once then clicks loudly a few times - I think the clicking is from the distributor.

My car misfired multiple times in two days i replaced coil 1 & 3 & it misfired again i took the coil that i replaced and put it back and the car was fine so. i don't think its the coils and i changed spark plug in coil 1, didn't work so I doubt it's coils.....

B5 Passat, it has the 2.8 and it has been having moments of shuttering so I did a scan and hit 3 engine falts, I did do a clear and rescan so these are new faults.
3 Faults Found:
17801 - Ignition Coil Power Output 1
P1393 - 35-00 - Electrical Malfunction
17802 - Ignition Coil Power Output 2
P1394 - 35-00 - Electrical Malfunction
17803 - Ignition Coil Power Output 3
P1395 - 35-10 - Electrical Malfunction - Intermittent
Right now my guess is the coil pack is going out or loose connection to the coil, this coil is roughly 8 months old so it kinda has me at a loss and hoping its not the coil.

I have a 2000 Staturn LW2 auto, 6cyl. When I try to turn on the car, sometimes the engine does not turn, doesn't make a sound, nothing. When I move the steering wheel, it turns on fine, it has to be in a certain position. Does that mean, the ignition switch is faulty or is it the pin? Is there a test I can do?

2001 MK4 GTI VR6 put brand new coil pack, wires and plugs in the car because it was misfiring. Was fine for about a week than I got a clogged cat code and could feel the affects. I now have no cat, no resonator, and no muffler. The car is finally driving good and then the check engine light came back. It says only a misfire in Cylinder #3 and when accelerate hard to speed up my check engine light starts to blink until I stop accelerating hard. So my guess is the clogged cat caused that cylinder to misfire but I do not know the actual solution to this. My EVAP hose is semi-pinched and when u squeeze it you can almost kill the engine. The weirdest thing of all is this: driving normal I shift in between 2000 and 3000 RPM and once i get into 4th gear about 2000 RPM......my car starts shaking badly and i feel like my engine is going to fall out. I have searched and the only thing i can think of is a bad injector...

Long story short, I had run down the HV battery in my 2001 Prius. It turned out to be a faulty wire to the ignition system of the ICE. While diagnosing, I let the HV battery drain, at least I think I did (Please see image of my HV battery specs). My question is, How can I charge the HV battery? I read Öut of Juice" but do not have the charger. My question is can I make one?

A friend of mine has an intermittent misfiring problem with his 2003 Passat 1.8T (manual). It occurs mainly at start-up when the engine is cold, and also sometimes at idle. After some research, we've found out that coil packs were a recurrent problem on some B5's, so my friend wants to take a chance and replace the coils.

I have a 2002 Camry 2.4L, ECM 89666-06220, ignition coil 90919-02243. One of the coils has gone out. I got a misfire code on P303. I then moved the cylinder 3 coil to cylinder 4, cleared the code and restarted the car. The new code was P304, bad coil. I found a set of low mileage used coils, 90080-19023. The dealer says this number was one of the three options for 2002. But the pin-to-pin ohm values don't match.
The 90080-19023 pin ohms, 1-2= 348, 1-3=667, 1-4= 490, 2-3= 1100, 2-4= 912, 3-4= open. The 90919-02243 pin ohms, 1-2= 390, 1-3= 673, 1-4=940, 2-3= 1154, 2-4=1403, 3-4= open. How to successfully do this substitution and not burned up ECM ?

The problem is there is no spark coming from the ignition coil. There is power going to the ignition coil but no spark. The car turns over but doesn't start.
I have replaced the crankshaft sensor and the Ignition Module. The wire that goes from the ignition module to the Ignition Coil has been replaced with a new wire that goes directly from the module to the coil .
Also the coil has been checked and its operating within parameters.

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.
