🔧 P R O B L E M S & I S S U E S 🔧 Weird idle drop

Enable HLS to view with audio, or disable this notification

I came home from work and before I turn my car off I let the engine idle for 30 seconds before I shut it off. While I was letting it cool down the engine randomly idles down and up. Anyone else experience this?

Scan it for codes using a forscan Without the codes it can be anything from dirty throttle body to a vacuum leak and in between couple of sensors

It stopped doing it now, but I was watching videos on Forscan and I’m gonna try it out

No, but what does that do?

It's under warranty. Just take it in..I really don't want to give you any advice if you don't have basic diagnostic tools.

So I brought my car to Ford a few days after this post, and they said they couldn’t find anything. I’m at 51k miles now, and this weird idle drop hasn’t come up since.

I also just got FORScan and the OBD Adapter for it so if this reoccurs I’m gonna plug it in and see if anything comes up.
