hey all, when my '99 4.0 OHV sits and idles for a bit i get a moan in the intake, but not all the time. i unplugged the IAC the other day when it was doing it and it shut up. when i plugged it back in right away it didn't do it any more. i was also told by the PO that it needs a fuel pressure regulator because it's hard to start. any thoughts?
as far as the hard start, it fires up pretty easily first thing in the morning. otherwise i have to crank it 3, 4, sometimes 5 times to get it to fire.
