I solved mysterious several problems by replacing the injectors with a good used set.
For the last 2 years I kept getting more and more frustrated with an idle problem. It would mis at idle at an irregular interval. I kept thinking it had to be something with the ignition, but not so. I ended up with a new motorcraft ingnition, one part at a time.
The car finally developed a leaking injector and I found a replacement set that completely solved the problem!!!
When I rebuilt the engine 2 years ago, I took the injectors to a shop and had them professionally cleaned and checked out. That's why I kept ruling them out as a cause of the problem. Now it seems obvious that they were the cause.
Right about the time it started to leak a little fuel I noticed that the trip computer showed that I had used 17 gallons, but I was putting in over 19 gallons. Normally that computer was right on the money so that was a strange thing to see. If it was leaking internally as well, that might have been right.
It never ran bad; it would just intermittently idle a bit rough.
Anyway, if anyone is trying to fix an irregular idle mis, it may just be your injectors.
