Seriouse problem with air intake and pre detonation

[mikeetown]

I'm going to get s youtube vid of this tomorrow. I've taken apart stuff 3 times now. Intake and all sensors and so on. My intake is leaking an excesive amount of air from inside the throttle body. Huge hissing sound.

My k8-ZE is pre detonating at random times. Sometimes a lot and sometimes a little. I'm so stuck and i'm so pissed cause i need a car running ASAP.

Please help guys. The vid i will post wil dumbfound you.

When i start the car it revs to 4000rpm right away, wont stay running unles the VAF is unplugged..... lol what the heck is going on!!

Mike,

Hissing should have given it away right off the bat. Check all the vacuum hoses for cracks. Find out where exactly the hissing is coming from. See if you can hook it up and check to see if its posting any codes too. Report back w/ your findings.

yeah vac leak for sure, check the 2 small vac lines that attach at the air filter box as well, I have knocked them off before when removing the filter and forgot to reattach them because I was in a rush, that caused a nice loud hiss as well.
