It's going to drive you crazy however, This may assist you....

2 weeks ago I filled up in Ohio retuning to Eastern PA. The next morning, I had the same issue you have.

I had the time so I ran injector cleaner through a tank of gas, replaced, The CHT, ICV and O2 sensor. Cleaned the Speed and ref. Sensors, all connector plugs cleaned and reset the idle.

I must say the idle was smooth as silk. The next morning, same thing. Stumbling for about 10 sec's and then running fine.

In the last few days, the problem is slowly going away.....

IT HAD TO BE BAD GAS.......I would run some techron through your tank and give it a couple of days.
