    I have a 2018 Raptor, truck has been at the Dealership as they can’t find the issue for the rough idle. Anyone else having this issue? At the moment the truck sounds like a diesel. Dealership thought it maybe issue with the injectors. 9k the issue happens when the engine is warm and cold....

    Just heard back from the dealership, it only took them a week. Possible reason for the noise is a slack timing chain. Fingers crossed this is the problem I'll keep this thread updated as and when I hear.

    That sounds like fishy to me, unless the tensioner let go, in which case the thing would sound like a bucket 'o' bolts. Does it smooth out above idle?

    Yeah noise disappears when you rev engine or when driving.

    Update from Ford Motor Co, they are authorizing the replacement of the VCT's whatever they might be! Timing chain was slack.
