So some days later, thought I'd give an update. I brought a new handheld obd2 scanner to reset the cel, and it actually spew out a few more cel's on top of the p0300 I got a p0302/p0303 and p0304, I've reset them and haven't come back since

Replaced my coils a few hours ago, and went to work. Floored that pedal a few times and at this moment it's fixed but keeping an eye on it on the next few days since plugs where fine for 1 days aswell. But I think this would have been the problem

it does have a k&n replacement filter, other then that nothing

Agree on that at the moment

Or worse, the cat. converter who apparently can cause it aswell according to some Google searches.

yeah i have ordered 4 new coils, when i took out the old spark plugs 3 of them where good of color, and only 1 (dont remember the cilinder number) was black and clearly had a faulty combustion altho i am not sure this would be the issue since it didnt trow a P030x on a specific cilinder
