Hey Scotty.
I have a '16 f150, 5.0, 71000. The truck has developed a rough idle and stalling issue at stops ( there are no warning lights or error codes). This issue happens several times a week. I have been to 2 separate ford dealers, and a local shop that I trust and have not gotten any results. The local shop has read the live data and of course the truck doesn't act up for them ( I have left it with them 3 times). The shop tells me that this is a known issue with Ford and that there isn't a fix. The truck runs beautifully when this issue doesn't raise its head. Any help, comments or advice is appreciated.
Thank you sir.
Thanks, today I replaced the vapor canister purge valve and the truck seems to be running better and smoother. It has not stalled yet, bet I have only been a few miles. Only time will tell.
Thank you!!
Did this help your problem? I am having a similar issue currently.
