What is your question?
So I have replaced All Plugs (Denso 5339) And all Coils (Karlyn 5104) Since this is the only brand Worldpac had available. Anyway, after all this, I am still getting a check engine light on for the same Cylinder 3 Missfire.
How long has your 2010 Mazda CX-7 had this problem?
Since last week
Sorry for not mentioning before but yes, the ECM was reset right after replacing coils and plugs and after driving a few miles the light came back on.
Ok, does it feel like the engine is actually misfiring .. Jerking or jumping sensation felt while driving at steady speeds?
'Possibly' a fuel injector problem on # 3 .. Recommend further diagnosis - probably need hands-on assistance from qualified personnel with proper testing equipment. Failing fuel injector will mimic ignition misfire!
