2004 Mazda 6 with a P0302 code.
Hi,how are you? The po302 code is a cylinder #2 misfire and on these vehicles the ignition coils are notorious for failing,the #2 ignition coil needs to be tested and is the most likely culprit.
Customer: replied 4 years ago.

Which one is #2 and should I replace all or just the one. Also , should I replace the plugs and which brand do you recommend.

I would recommend replacing just the one coil and all of the spark plugs with NGK plugs,give me just a few minutes and I will get the firing order for you and the location of #2
