No codes, missing

[Neo]

My Ford 2001 F150 4.6L V8 is missing and has never turned on the check-engine light, or produced a code. It has 114,000 miles.It runs ok cold, misses slightly at idle and at almost any speed, although 35-45 seems worse. It’s not bad, it’s just constant. A few times is seemed serious, but then is settled back into annoying.I have an Autozone handheld OBD tool, and it seems to work ok, but the handheld reader has never shown a code, hard or pending. The Check Engine light is off.I’ve replaced the plugs, COPs, and Injectors – the truck still misses. I’ve Cleaned the MAF (with MAF cleaner) and all the filters have been changed regularly.What product would I need to diagnose, or at least be able to read the Ford data?Thanks

Now THAT is a happy ending. Don’t forget to change the ‘traffic light’ to green now that the issue has been solved.
