ALright, my brother took my GSR for the weekend to wash it and such while I was out of town, and he re-routed the misc. hoses that went over/aroudn the IM to underneath it. Now the central hose (is this is hose to the PCV valve) is crimped down the middle. And whenever I have my car ina high gear w/ low RPM's, and I give it throttle, there's like a sort or rubber-ish popping in my engine bay. It sounds like someone is flicking the end of a rubber tube really fast. I believe it may be the crimped house expanding and compressing, but have no idea, any help?

I'd probably reroute them back the way they to the way they were. what year gsr is it?

 

'97, and yeah, I'm gonna do that ASAP

 

Emmmm...this may seem like a stupid question, but why on earth would he have to re-route or even touch vacuum hoses to wash a car...TBH i would tell him to stay the hell away from your car in future...god know what he may do next time he washes it...dis-connect brake lines????

 

If it's crimped in the middle just get a new hose and see if the problem goes away.
