Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

new car to me, PPI-Lite gave me the misfire codes but when I inspected the car, the coils were cracked so I assumed that was the cause.

Could I ask someone with more experience reviewing the actuals to comment on the misfire patterns in the attached reports and let me know if they have any idea of what I should be checking next?
Leading evidence: 'Inspect car, the coils were cracked so i assumed' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check next' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

I've run 3 cans of Seaform, cleaned the throtte body and MAF and everything is functioning (from what I can tell from the Actuals reports from the Durametric).
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Hello Gents. I have been tracing a continuous PO300 fault code for a couple of months now... Backstory.... new car to me, PPI-Lite gave me the misfire codes but when I inspected the car, the coils were cracked so I assumed that was the cause. I replaced all the coils and plugs (correct part numbers) and within a few weeks the CEL light came back on.
I then purchased a Durmetric started trying to trace the codes... the misfires appear to happen during start-up and just off idle. I get an occasional stutter if I pull from a stop in first gear with revs below 1200rpms.
I've run 3 cans of Seaform, cleaned the throtte body and MAF and everything is functioning (from what I can tell from the Actuals reports from the Durametric). I'm not pro and am just becoming acquainted with the 996 and I hate the idea of not being able to fix this without going to my independent.
Could I ask someone with more experience reviewing the actuals to comment on the misfire patterns in the attached reports and let me know if they have any idea of what I should be checking next?
The engine pulls strong and is smooth. The idle is pretty steady when cold (1100-1175rpm) drops down to 700-800rpm) when warmed up. Not oil burn, cross contamination in the coolant or oil tube. The cam variation looks on spec in the reports... I just don't know what to look at next.
Thank you in advance... PS this is cross-posted on Renntech as well and have been getting lots of help there but I'm getting to a dead end. Hoped someone here might have a good idea.
This site doesn't allow me to upload files other than images so I created a public drop box where you can access the Fault Codes in PDF and the Actual Values in different text parameters across multiple date and start up conditions.
