i own a 01 929 and recently the idle its been runing rough and after a one or two minutes stalls. i start it again and it does it well but the idle still rough. i though the problem was the pc so i took it off but still. i found a similar post and the guy says to pull off the hose from the fuel pressure regulator and if any fuel comes out its a bad regulator but theres is no fuel coming out but (again) when i took off the hose the idle just went right, put the hose again into the regulator and the idle went bananas. its a bad fuel pressure regulator? if it is, this guy says that it should have fuel coming out, but theres none.
