Last two months i have a problem with ignition coils.
i bought many times from US and UK market aftermarket coils and was working fine.
but the last 2-3 times the coils which i bought from the same sellers are showing very stupid problem , the new coils are working fine on the car BUT after driving 10 minutes i got the cel on , the diagnostic tool giving this codes:
P0355,P0351,P0353,P0352 and the engine still working fine.


also to let you know:
tested on different cars
tested one by one on a good engine with new plugs and leads.



if anyone got something similar please let me know because i am trying to solve this issue.

 

8/10 of rx8s in Cyprus are Japan importer 1/10 Uk and the other 1/10 are new from Mazda Cyprus.
but i am sure that i used coils imported from UK and US on Japan rx8's and was fine until now.

 

i mean you are correct, the rx8s here are Japan specs but many times bought coils from us and uk and worked fine !
