Excellent tutorial Jake. 100% correct on all you said. My ‘06 Cayman had 6 new coil packs fitted by an independent but later showed a misfire on 4, plus engine warning light.🤯 Checked by a different garage, resulting in removing a badly fitted coil pack which had snapped off a big chunk at the connector end. Every time I hit a rough road surface, misfiring occurred because of poor connection just as you said. Subscribed for more first class explanations.🇬🇧
My mechanic just recommended I replace these to the tune of almost $1k. Needless to say I’ll be attempting them myself. So this couldn’t have come at a better time. Thanks.
Outstanding Video ! Jake !! Remember a few years ago when I called you about my miss fire. It was the #1 Coil Pack. At your suggestion , I replaced all 6 ,, No problems since!

I wandered around the net for a while looking for a clear view to R & R spark plugs on my 03 Carrera. I got a cyl misfire code on #1 last night, so figure I'm heading this direction. The lack of camera access to cylinder 4 glosses seems to gloss over the widely reported difficulty of access and why everyone else seems to wander down the rabbit hole of exhaust removal. Raby even does it with the wheels on! Gotta love having a lift. Thanks for giving me more confidence to do this plus the spark plugs while I'm at it.
As the producer of this video, I can attest to the fact that Jake Raby was able to remove and install all 6 coil packs on the 996 without having to remove the exhausts. Of course, #4 was the most difficult because of the engine layout and because of the lack of space I was unable to get a clear shot of him installing it. My cameras are big. Hindsight, I would have brought a GoPro, but even then, it would have been a challenge. Good luck!
Thanks for your reply. I really appreciate your video! It gave me the courage to try the job and I competed it yesterday. It took me about 4 1/2 hours. You are right. No need to remove the muffler. What helped a lot was seeing you do the job without jacking up the car or removing the wheels. I backed the car up on ramps and lay under the back of the car. This gave me good access to the plugs. I recommend starting on the drivers side with the rear most plug and coil. This gives you experience as you move forward and also schools you on the passenger side rear plug because by the time you get there you will know the flow. For others trying this - you can reach the rear plug on the drivers side both with your left hand from the front and your right hand coming up behind and through the exhaust. I used a 3 inch extension and a flex joint spark plug socket. The dream tool would be a 4 inch extension plus the flex joint socket. This would help your ratchet handle clear the other electrical sensors adjacent to the plug bays. DUCT TAPE YOUR SPARK PLUG SOCKET TO YOUR EXTENSION! I had never tried this, but it saved me tons of pain trying to remove the spark plug socket from the spark plug after installation. I saw this on another RUclips video and it is a lifesaver. When it came to the passenger side rear spark plug, the biggest problem was not removing the plug. Since I learned so much by doing the driver side, it was actually pretty easy to remove it. I had access with my right hand from the front with a little help from my left hand in the back. The hardest part was walking the rubber boot back on the coil plug! It took 30 minutes trying to bring it back down. Do yourself a favor and grab a small needle nose pliers to pull it back down if you have trouble. I was able to get a torque wrench to the passenger side rear plug, but there was too much slop in the torque wrench to get it to click given the limited amount of vertical up and down space with the torque wrench coming off to the right. My workaround is that I helped the torque wrench with my right hand and with my left hand I popped off the head of rachet, turned the ratchet head with my fingers while holding the handle as far up in the engine as possible. This would reset the ratchet teeth enough to have resistance at the top of the stroke instead of slop as I pulled down. If you don’t know what I’m talking about, you might know once you get into it. This method also works as you move to the middle spark plugs. Once again, this job was easier than I expected. I had done the plugs in my 97 Boxster also so I have some experience working on my cars. Just get comfy on your back under the engine and be patient.
Yes, I can confirm that a full Porsche M96 rebuild video series is in the scripting/planning stage for filming this month and ready for sale later this fall.
Thanks for the video, was very helpful. Got all 6 coils out without wheel or muffler removal. Half way through the job, hope the coils go back as just as easy and this fixes the misfire.
Hi. Jake Raby has decided to not give out torque values because they change when the manufacturer improve fasteners and other parts. The best resource guide for torque values is sold by LN Engineering. It has all torque values on the M9X series of Porsches engine. This book is kept up to date as torque values change. lnengineering.com/education/literature/996-997-torque-book-bundle-fastening-specifications-for-porsche-911-types-996-997-automobile.html
Shaking at idle with no codes also possible? Have a broken tab on one coil connector I'd like to replace to see if that fixes it....are connectors also replaceable with the engine in the car?
Thanks Jake. How easy to remove the coil pack #4 without removing the wheels, muffler and bumper? I have a 06 997.1 C4S that I plan to replace the spark plugs soon.
Cylinder #4 is the most difficult because of the M9X layout on bank 2 which makes it a very tight fit, but with patience it can be done without having to remove any exhaust components or bumper as shown in the video. You may find it easier unplugging and reconnecting the #4 coil pack from the top of the engine.
Hi . I have a 1999 boxster 2.5 litre. codes im getting are misfires on cylinders 4 5 and 6. I found that the exterior of coil number 4 has cracks in it. Also getting 02 code saying " O2 sensor ahead of catalytic converter. cylinder (4 to 6)" . Any ideas. Thanks
Hi a thank you so much Jake! Sorry about my poor American. Can you please confirm me a coil pack problem with this videos: 1°/ Start Engine: ruclips.net/video/eMoMk8mRxlM/видео.html 2°/ Medium Temperature. After 3min. I have an unstable idle. And vibs are coming : ruclips.net/video/sH-Q0giwjoE/видео.html 3°/ Hot Engine: ruclips.net/video/AXnNkJIo2gQ/видео.html Many many many many thanks for your helps.
The coil packs were the factory originals. That means 17 years old at the recording of this video. Only the factory OEM original come with the triangular Porsche logo (notice on camera). Coil packs are subject to many heat and cold cycles which ages the plastic housing. Over time, the plastic housing cracks which make the coil pack cause a misfire.
@@RennvisionbyTheKnowledgeGruppe So many many many thanks! I totally agree with you. I have an O2 sensor to change to. The engine is new replacement by Porsche in 2011. So with noise you can hear, you don't think there'is problem with Timing Chain, Variocam, IMS or important issue ?

i like the approach you're taking now since most people that have these cars now are not dentist but enthusiasts

The most common reason for misfires is faulty coil packs. Glad to hear the video was useful for you.

@@RennvisionbyTheKnowledgeGruppe That's what i've been waiting for since i cant make it to Georgia!

Thank you! One of my plugs wasn't connected hence why I had misfires.
You're welcome!
Great video. What is the torque setting for the coil packs?
Hi. Jake Raby has decided to not give out torque values because they change when the manufacturer improve fasteners and other parts. The best resource guide for torque values is sold by LN Engineering. It has all torque values on the M9X series of Porsches engine. This book is kept up to date as torque values change. lnengineering.com/education/literature/996-997-torque-book-bundle-fastening-specifications-for-porsche-911-types-996-997-automobile.html
Jake does actually mention a torque setting value of 10Nm at 8min into the vid.
Why aren't you replacing the spark plugs while you're there?
Because this is a video about swapping out coil packs when a misfire is detected. This can occur with brand new spark plugs.
Shaking at idle with no codes also possible? Have a broken tab on one coil connector I'd like to replace to see if that fixes it....are connectors also replaceable with the engine in the car?
What causes these Coil packs to crack like that
Age, heat, vibration, etc.
Thanks Jake. How easy to remove the coil pack #4 without removing the wheels, muffler and bumper? I have a 06 997.1 C4S that I plan to replace the spark plugs soon.
Cylinder #4 is the most difficult because of the M9X layout on bank 2 which makes it a very tight fit, but with patience it can be done without having to remove any exhaust components or bumper as shown in the video. You may find it easier unplugging and reconnecting the #4 coil pack from the top of the engine.
Is the 0300 a generic misfire code while the P0302, P0304... Refer to which cylinder the misfire is specifically on?
Yes, 0300 is multiple misfires and 301 - 306 are specific to the cylinder.
@@RennvisionbyTheKnowledgeGruppe thank you
You mention that the coil packs should be (proactively) replaced periodically...How often would you suggest?
Hi . I have a 1999 boxster 2.5 litre. codes im getting are misfires on cylinders 4 5 and 6. I found that the exterior of coil number 4 has cracks in it. Also getting 02 code saying " O2 sensor ahead of catalytic converter. cylinder (4 to 6)" . Any ideas. Thanks
