Keep throwing parts at it until you find the problem. No need for any kind of diagnostic work, that's just craziness.

i had similar problem after reset of the ECU, my IAT and TPS was bad. I got new but that TPS was bad to. After changing to 100% good IAT and TPS it was fine. Dont buy cheap sensors. Remember to reset ECU after replacing sensors.
