P0303 Misfire with Hondata TC Activation?
P0303 Misfire with Hondata TC Activation?
Did a quick WOT on some known slippery pavement and popped a P0303, Coils & plugs were serviced not so long ago - Just wondering if it's possible that the TC Activation may have triggered the code?

Post the calibration and a datalog showing the issue.

I had a hunch; Turns out there was standing water (!!!) the depth of the spark plug in Cyl 2 & 3 - Novel, as it hasn't been washed / engine bay washed etc, silicone on the spark seals etc.
(Definitely rain water as well, I had a little taste after pumping it out :D )
Pumped it out, dried the coils and plugs.
I've grabbed a datalog for entertainment value after I test drove it tonight; Still misfiring so I've ordered some new coils - The plugs look clean still, So I'll have them out when I swap and see if they are salvagable with a clean up.
No knock retard on the datalogs, and it doesn't look too lean either which is interesting, just sits with Tplate 99% and no commensurate gain in speed.
