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.
