First thing, are there any codes? With the way you are describing it, there should be codes. MIL ever come on, flash?
If you replaced the maf, was it aftermarket or porsche? exact same pn?
cps wont be the issue cause the car starts
o2 sensor - maybe but you need to look at fuel trims & all of the voltages....or just throw parts at it
icv - There isn't one
throttle body - never hurts to clean it properly
fuel pump relay - doubt it,the car starts & runs
injector - possible
intake leak - possible
Proper diag is needed before just doing things.
Video also helps to show what it is you mean. You say constant throttle it is ok, but that is putting load on the car...then you say putting load on the car causes it. Kind of confusing with that. Load is anything above idle.
