Default SC300 manual; idle low and dies.

I bought the car like this and alot of parts have been changed. This is what has been changed to my knowledge.

-Spark plugs
-Spark Plugs Wires
-Distributor Cap
-Distributor Rotor
-Air Filter
-Cluster lights (new tachometer and speedometer motors)
-AC Unit lights
-Transmission Fluid (Mobile 1 75W90)
-Differential Fluid (Mobile 1 75W90)
-New Fuel Filter (OEM)
-New Fuel Pump (Walbro HP 450 E85 Rated)
-12V fuel pump mod
-New trunk struts
-New hood struts
-OBDI Bluetooth dongle connection

It ran fine for a month. Now, the car turns on everytime but as the Rpms drop and the car dies constantly. I don't know what to do anymore, the car is pretty much un-driveable.

The car starts to shake at 200rpm and then dies, AT TIMES. Now, it just turns on and dies.

Help

id clean and check the intake manifold and also test your TPS and IACV to make sure they are receiving proper voltage and clean them both if possible. I know im going to seem like a broken record but check the ecu as well for leaky caps. Its so common now and fixes alot of issues.
What year is the car?
