My 99sd runs good till it warms up then it has a miss. When you start off it misses but smooths out when going down the road. Just does it when I'm creeping around. Any idea what it might be. I have a scan gauge but I found out it won't work on a ford ps.
Mine started out the same way, but eventually got worse. Try cheaper routes like EBP tube/sensor. Everything now on mine is pointing to injector issues, will know more today hopefully. Try that cleaning that tube. Usually this is gonna fix it.
