I had the same exact problem as a lot of people here, i traded a rotting out 98 vw golf for my 2003 zx3 and heard the hissing, my mechanic friend sprayed the intake manifold with cleaner and heard the change in idle and thought it was thought. my other friend and I took off the manifold and saw the cracked pcv hose, so we came on here, read this thread, bought the toyota hose, and will hopefully be putting it back together today.
