Clogged PCV hose?
I'm wondering if the OEM PCV hose (passenger side) is supposed to restrict the amount of air it passes through or if mine was clogged? When i changed out my hoses with Z1 silicone hoses I noticed the OEM was very restricted and the Z1 was wide open.
What's interesting is that i felt an improvement in throttle response after swapping out my vacuum hoses. I did a few other things, so I can't pinpoint what exactly helped with my car bogging down low. If the OEM hose is indeed supposed to be unrestricted, I was being robbed of power from this clog.
I suggest you take a look at the hose coming off the plenum into the battery area (goes to brake booster). This could help someone tracking down a hesitation in the lower RPMS.
