Default CEL Code P0301

Anyone know what could cause this or what I should change?

Car has 32,1xx miles
Installed AEM V2 2 weeks ago (no cel then)
no other engine mods

I ordered spark plugs a lil while ago and planned on changing them even though its not needed. do you think this will fix it or am i better off taking it to the dealer? Thanks!

check the spark plugs and make sure clyinder #1 isn't loose. also check the plug for unusual wear. you could also swap the coils from cylinder #1 with another cylinder, then clear the code and see if it reoccurs on the same cylinder. this would tell you if it's a bad ignition coil. you could have a bad ECU too. there's several things it could be obviously, so taking it to the dealer might be your best course of action.

Do you drive it in the winter? or store it? Check injectors, ohm them out they should be 10-13ohm's if they are higher than that run Chevron's Techtron injector cleaner. This is what was recommend by our Honda rep.

my car was stored in winter. for 4 months to be exact. i have new spark plugs that will come in tom. i will go buy some fuel injector cleaner. i cleared the code and have ran my car for 2 days now with no problems. my car never felt different before and runs fine. i guess it was an ecu mishap or something?
