stalls on idle

[boxster newbie]

here we go again 97 boxster, 245,000 ks. engine swap at 140,000. ims issue. no porsche fix though they instaled a low mile donor engine...previous owner had same problem an indie shop, changed mas, and fuel pump. i have done this twice myself, last pump, and mas both bosch, done ten months ago, have done crank sensors , fuel relays, caps, etc. but it seems to come back to the pump and mas. frustrating

i am wondering, if putting in a bosch fuel pump is a mistake. should i have sprung for the porsche part. is their a difference? i was under the impression that bosch made them all?

Instead of fretting about it, check your fuel delivery rate and pressures; if both are fine, it does not matter who made the pump...………..
