Question about Ford Taurus
You may want to give us a year,make,model,engine & start over
The motor doesn't know the brand of the plugs you install
You sort of on a guessing trip here
Need in exact detail what was tested & how & the results
Be nice to know what your problem was before you started

I'm sure you have installed a fuel pressure gauge and monitored the fuel pressure while the problem is occurring?Another diagnostic tool which is easy to do,is while the problem is occurring,unplug one sensor at a time beginning with the Mass Air Flow first,.if it uses one.Many times,not always,depending on the sensor,if the sensor is taken out of the picture as far as what the PCM is seeing,like unplugging the MAF,the PCM will substitute the missing sensor output with a generic value that will allow the engine to at least run,and if unplugging for example the MAF,the engine idle speed returns to normal,you know you're onto the problem.You didn't mention if the engine ran ok other than the idle problem.As far as checking for vacuum leaks,i use something like brake cleaner or WD 40,more of a liquid,and it does sound like a vacuum leak.Plastic intake manifolds do develop nearly invisible cracks that open up more with heat.Revsisit the possibility.And as for the PCM,it is possible,but more likely a mechanical problem.Lastly,remove an O2 sensor or two before the catalytic convertor,run the engine and see if anything changes.Cheap way to verify the catalytic convertor is flowing and not restricting engine airflow,as i have seen bad cats cause misfire codes and strange problems.Good luck.

When you say tried different radio and it didn't work, does this mean the tuner acts like it is functioning, but you hear nothing out of the speakers?
If so, this stinks of a bad ANTENNA...

The .030 may cause a too rapid burn time condition. And Yeah, .060 is standard GM on almost any make/model nowdays.. It may be one of ur coils.. but that would show an individual cylinder.. Try the .060's and let me know.. esp if it wasnt doing it before
