Irregular Idle help
I have an 05 f150 with the 5.4l with 113k miles on it. It normally idles perfectly, but occasionally engine speed drops about 100rpm and wavers slightly with a rough idle, but then gradually evens out to normal idle, and repeats. I haven't been able to isolate whether this happens in warm vs cool temperatures but i've been able to recreate it in Park, Neutral, And Drive. This is really the first computer controlled car I've dug into so I'm lookin for anything, don't be afraid to dumb down your answers.
My mind first went to a missfire, other threads here have also talked about clogged injectors, MAF, and IAC.
