New search for vaacum leaks. None found.
If I disconnect the MAF when it idles it immediately stops.
Also opened the oil filler cap when it was idling. Not difficult to open. But some suction there. The idle jumped up to 1500 With the cap open.
Will change fuel filter tomorrow, just in case.

Are you disconnection the MAF while it is running??? Or disconnecting then starting the car and it dies?
Unplug it with engine off.
Then start car and see how it runs.
If it runs badly or dies then I would say it is starting to sound like the MAF could be the issue.
Usually when you unplug a faulty MAF the car runs better.
But you have those intake mods so I am thinking the opposite will happen because the DME defaults to openloop fuel maps when you unplug the MAF.
So I would check and clean the IACV first. Just to be sure it is not the problem.
No cost in checking and cleaning the IACV.
MAF sensors on the other hand can be a little pricey.
