I replaced the batter a couple weeks ago with a non-AGM battery, I wonder if that could be some of it, but that should affect both banks.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

On my 2002, with a flat6 rebuilt engine, the literature with the car says to use the early 996 spark plugs, with no part number listed.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

On my 2002, with a flat6 rebuilt engine, the literature with the car says to use the early 996 spark plugs, with no part number listed. They seem to be a bit harder to find. According to the Bentley manual, the 3.6 uses Bosch FGR 5KQEO 3.4 uses Beru 14FGR-6KQU. Any thoughts on the difference in the two plugs, or rational for the older plug? Thanks in advance

POST 2Original post

Submit a ticket to Jake and i'm sure he will give you an answer, best to go to the source since it's his engine. Good luck

POST 3Original post

The early 3.4 Spark plugs are one heat range "cooler".. Cooler plugs are needed if compression ratio is increased or horsepower increased..

POST 4Original post

...as in Flat 6 Innovations? Then like Optionman1 said, open a ticket there and ask Jake. Jake's recommendation for his engines > Porsche documentation from 19 years ago.(or 9 hours ago)

POST 5 / ORIGINAL POSTEROriginal post

Great, thank you. Makes sense. Will get these Bosch FGR-6-KQE, unless there is another opinion. The response I got was that I needed to check the documentation, and that they not responsive to subsequent owners. thanks again

POST 6 / ORIGINAL POSTEROriginal post

Here is another dimension to the misfire problem, I changed 2 of the coils on the left bank a few weeks ago, 1 and 3 if I recall correctly. Pulling the muffler off helped tremendously and took 10 minutes. I am getting a misfire on cylinder 1 and sometimes cylinder 2, only after restarting after driving it for a while. Once i clear the codes it drives fine, but if I stop somewhere and restart it, it throws a code. It definitely runs poorly when there is a code, when there are no codes, it seems to run fine. At first I thought it may be water, but the last couple drives have been dry. I replaced the batter a couple weeks ago with a non-AGM battery, I wonder if that could be some of it, but that should affect both banks. I have more coil packs and spark plugs coming, but the more I think about it, the more I am convinced it is is not the issue. I am planning on inspecting the wiring as far as I can see, maybe there is a short somewhere? Do people use any sort of dielectric grease or other connection prep on the wiring, coils? Any other thoughts on this issue? Side note, the side blinkers do not work, both sides. Fuse is fine, the front and rear blinkers work. It appears the side wiring is not getting juice. Any other ideas of where to look? I did not see a separate relay or other component that could fail and the others still work. Or, am I testing these incorrectly? Maybe its the crocs?

Ground to the chassis to rule out s bad ground. The headlight and ignition switches cause all kinds of crazy random issues with our cars.

POST 8Original post

The lights on the fenders are marker lights, not blinkers for USA cars. They should light up with the other marker & tail lights. They don't light up with the turn signals.

POST 9 / ORIGINAL POSTEROriginal post

Thanks, they work fine in that capacity. I am not sure why I assumed they would be side indicators.

POST 10Original post

The ROW cars have them wired as turn signals. It is not something that can be "coded" in the 996 - they are hardwired.
