Default Car Shuts off when idleing (K&N intake system)

i noticed when im stopped, at a light or stop sign, after a few seconds my car starts to loose revs and it dies. It will stay on if i rev it but if i do nothing it just seems to idle below 500rpm and cut off. It always comes back on with no issue. What could this be?

It also cutts off when I start it up the next. It will stay on if I keep revving it.

IAC valve on the Throttle Body.

Most likely gunked up with carbon and not functioning properly.

I bought a New K&N filter. I thought it was the filter at first, because when I installed the filter the car started without shutting down and without me revving it. And it been two whole days without me starting the vehicle.
It been two and in a half years without me doing a tune up. I have MSD wiring and they look pretty decent. For the oil, I keep up with the oil.

Where would that be located at?

Agree on the MAF but with the idle dying slowly like he says unless he steps on the gas, it's sounds more IAC related since the whole point of that valve is to control air when idle.

Clean the IAC, it's pretty much an easy freebie. If that doesn't do it, I would consider a new fuel filter (I know it's a different car, but I had those same symptoms with my '84 Camaro years ago, changed the fuel filter, no more issues).
