So last week I got a random code "P112F". So then I reset it.
then a day or two after that, I received 2 codes "P112E & P112E P/D"
Which was a rough ride, So I reset it with the OBD scanner and went away and Drives perfectly normal.

Until today, I'm driving and get the Engine Malfunction. Driving a little rough, and whenever I come to a stop or a slow roll, You can hear the engine reving up and down by itself and idling rough, and acting twitchy.

I've experienced this before from last year because it was from the spark plugs.
And the only way I knew was from the code I got, telling me it was a misfire on cylinder 5.

But now, my car is acting up but with no codes or anything. I drove with it for 30 minutes and nothing was showing up.

*I'm going to put this out there, I think It's the coils. But I don't know. I've never switched them out yet.

someone let me know what you think, I feel like it could be also the fuel injectors, who knows...
