900 rpm idle and how to lower it? 5.4l
Ford f150 2010 5.4L V8 155,000 miles
I have an idle at 900 rpm and also have a random spike in rpm when on the highway and a slight jerk. Could this be a vacuum leak? I’m pretty sure there’s no IAC in the newer 5.4’s so I’m not really sure what to do to resolve this. Any help would be appreciated!
