Ok
That's an indication we have not solved it..
What we are looking for is unmetered air ..Here is another common possible. The cross over pipe from the MAF.. it should have good connections at the MAF, a little further up the line you will see an Air Temp sensor..make sure that is tight , and finally . [ and this is common] where the hose finally clamps to the intake there is a round clamp about 3" in diam..this has to be tight and you can only tighten it by sneeking in there with a long screwdriver from the front of the engine..try that..
You may also want to cap that purge and try a few trips w/o it.
Did you do the CRC MAF cleaning I mentioned..???

...and , check you do not have a dirty air filter.
